Steps to Solve Integration Function using Trapezoidal Rule

Follow these simple and easy guidelines to solve any function integration using trapezoidal rule manually.

  • Take any function f(x) with integration and lower, upper limits i.e a,b.
  • Also, know the number of trapezoids n.
  • The formula to compute trapezoidal rule of any function is
  • ab f(x)dx ≈ Δx/2 [f(x0) + 2f(x1) + 2f(x2)+. . . +2f(xn-1) + f(xn)
  • Where, Δx = (b-a)/n.
  • Divide the given interval into n portions of length Δx.
  • In the subintervals last one is b and first one is a.
  • Evaluate the functions at those subinterval values.
  • Substitute the obtained values in the formula of trapezoidal rule and sum up the values to get the approximate value.


Question: Use the Trapezoidal Rule with n = 5 to approximate ∫a=0b=1 √(1+sin3(x).


Given that,

function f(x) = √(1+sin3(x)

a= 0, b= 1, n=5.

Trapezoidal Rule dtates that

ab f(x)dx ≈ Δx/2 [f(x0) + 2f(x1) + 2f(x2)+. . . +2f(xn-1) + f(xn), where

Δx = (b-a)/n

Substitute the given values in above formula to get Δx value.

Δx = 1-0/5 = 1/5

Divide the interval [0,1] into n=5 subintervals of length Δx=1/5, with the following endpoints:

a = 0, 1/5, 2/5, 3/5, 4/5, 1= b

Evaluate the function at these end points:

f(x0) = f(a) = f(0) = √(1+sin3(0) = 1

2f(x1) = 2f(1/5) = 2√(1+sin3(1/5) = 2.00782606791279

2f(x2) = 2f(2/5) = 2√(1+sin3(2/5) = 2.05820697233265

2f(x3) = 2f(3/5) = 2√(1+sin3(3/5) = 2.17257446116512

2f(x4) = 2f(4/5) = 2√(1+sin3(4/5) = 2.34021475342487

f(x5) = f(1) = 2√(1+sin3(1) = 1.26325897447473

Δx/2 = 1/10

Finally sum up the above values and multiply by Δx/2

= ⅒ (1 + 2.00782606791279 + 2.05820697233265 + 2.17257446116512 + 2.34021475342487 + 1.26325897447473)

= 1.08420812293102

By checking the below sections, you will get a good knowledge on the parabola equation concept and you will also obtain a handy calculator tool that gives result in fraction of seconds.

How to Solve the Parabola Equation?

We can find the x intercept, y intercept, vertex, focus, directrix, axis of symmetry using any parabola equation in the form of y = ax2 + bx + c. In the following sections, we are providing the simple steps to find all those parameters of parabola equation. Follow them while solving the equation.

  • At first, take any parabola equation.
  • Find out a, b, c values in the given equation
  • Substitute those values in the below formulae
  • Vertex v (h, k).
  • h = -b / (2a), k = c – b2 / (4a).
  • Focus of the x coordinate is -b/2a.
  • Focus of the y coordinate is c – (b2 – 1)/ (4a)
  • Then, focus is (x, y)
  • Directrix equation y = c – (b2 + 1) / (4a)
  • Axis of symmetry is -b/ 2a.
  • Solve the y intercept by keeping x = 0 in the parabola equation.
  • Perform all mathematical operations to get the required values.


Question 1: Find vertex, focus, y-intercept, x-intercept, directrix, and axis of symmetry for the parabola equation y = 5x2 + 4x + 10?


Given Parabola equation is y = 5x2 + 4x + 10

The standard form of the equation is y = ax2 + bx + c

So, a = 5, b = 4, c = 10

The parabola equation in vertex form is y = a(x-h)2 + k

h = -b / (2a) = -4 / (2.5)

= -2/5

k = c – b2 / (4a)

= 10 – 42 / (4.5)

= 10- 16 / 20 = 10*20 – 16 / 20

= 184/ 20 = 46/5

y = 5(x-(-2/5))2 + 46/5

= 5(x+2/5)2 + 46/5

Vertex is (-2/5, 46/5)

The focus of x coordinate = -b/ 2a = -2/5

Focus of y coordinate is = c – (b2 – 1)/ (4a)

= 10 – (16 – 1) / (4.5)

= 10 – 15/20

= 37/4

Focus is (-2/5, 37/4)

Directrix equation y = c – (b2 + 1) / (4a)

= 10 – (42 + 1) / (4.5)

= 10 – 17 / 20

=200 – 17 / 20


Axis of Symmetry = -b/ 2a = -2/5

To get y-intercept put x = 0 in the equation

y = 5(0)2 + 4(0) + 10

y = 10

To get x-intercept put y = 0 in the equation

0 = 5x2 + 4x + 10

No x-intercept.

Question 2: Find the equation, focus, axis of symmetry, vertex, directrix, focal parameter, x-intercepts, y-intercepts of the parabola that passes through the points (1,4), (2,9), (−1,6)?


Given points are (1,4), (2,9), (−1,6)

The standard form of the equation of the parabola is y = ax2 + bx + c

When the parabola passes through the point (1,4) then, 4 = a+b+c

when the parabola passes through the point (2,9), then 9 = a(2)2 + b(2) + c = 4a + 2b + c

when the parabola passes through the point (-1,6), then 6 = a – b + c

Solve first and third equation

a + b+ c = 4

a – b + c = 6

2(a + c) = 10

a + c = 10/2 = 5

substitute a + c = 5 in first equation

5 + b = 4

b = 4-5

b = -1

Put a = 5-c, b = -1 in second equation

4(5- c) -2 + c = 9

20 – 4c -2 +c = 9

18 – 3c = 9

18-9 = 3c

c = 3

Substitute b = -1 c = 3 in the third equation

a +1 + 3 = 6

a + 4 = 6

a = 2

Put a =2, b = -1, c = 3 in the standard form of parabola equation

y = 2x2 – x + 3

The parabola equation in vertex form is y = a(x-h)2 + k

h = -b / (2a) = 1/4

k = c – b2 / (4a) = 3 – 1 / 8 = 23/8

y = 2(x-1/4)2 + 23/8

Vertex is (1/4, 23/8)

The focus of x coordinate = -b/ 2a = 1/4

Focus of y coordinate is = c – (b2 – 1)/ (4a)

= 3 – (1 – 1) / (4.2)

= 3/8

Focus is (1/4, 3/8)

Directrix equation y = c – (b2 + 1) / (4a)

= 3 – (1 + 1) / (4.2)

= 3-2/8

=24-2/8 = 22/8 = 11/4

Axis of Symmetry = -b/ 2a = 1/4

To get y-intercept put x = 0 in the equation

y = 2(0)2 – 0 + 3

y = 3

y intercept (0, 3)

To get x-intercept put y = 0 in the equation

0 = 2x2 – x + 3

No x-intercept.

Convert CGPA to Percentage | How to Calculate CGPA from Percentage?

Convert CGPA to Percentage

Convert CGPA to Percentage: Every year, the count of students increases appearing for CBSE exams. However, they have much stress in their minds as rewarding marks changes after some years. Thus students need to be very careful in every aspect. However, the system of CGPA calculation confuses them a bit. The feeling is quite different when they think of the final CGPA for their preparation.

However, this system of CGPA put minds to think about calculating the final percentage in every subject. Results are even more important if you are planning to study abroad. International universities demand high previous class scores and standard test results. Most of them also raise the demand for good CGPA. However, the term seems to be quite confusing. But we have tried to resolve it through the blog below. Below you will understand the important aspects while converting CGPA into a percentage.

How Can You Convert CGPA to Percentage?

According to the Central Board of Secondary Education’s terms and conditions, you need to multiply CGPA by 9.5 to get your percentage. Let us consider an example. Suppose your CGPA is 9.4, then multiply it with 9.5, and the resultant 89.3 is our percentage.

What does CGPA Actually Define?

CGPA is a Cumulative Grade Point Average. Before you start converting your CGPA into a percentage, it is imperative to define CGPA. Usually, we see CGPA results on our 10th result card. We define CGPA as the average of the collective grade points that we score in the subjects in a year. The grading system is supported by CBSE, which is allotted based on a range of marks. Take an example of grade A. It is allotted to the students obtaining marks between 90-95. Thus their grade point will be 9.

Now, if you have your grade points, how will you calculate CGPA with it? Take the example of a total of 5 subjects. You have grade points of each, and CGPA is the average of all. Sum your grade points and divide by 5. This is how you obtain CGPA. Similarly, if you want to find a percentage in each subject, multiply each grade point by 9.5.

CGPA to Percentage

Which is the Right Formula to Convert CGPA to Percentage?

The basic formula of calculating CGPA is through grade points scored in each subject which is further calculated based on a range of marks. Get the grade points of all, add them and divide by a total number of subjects. This is how you calculate your CGPA. Further, to calculate the percentage, multiply your CGPA by 9.5, and the resultant is your percentage.

Some Important Examples of Calculating CGPA to Percentage

Example 1

Calculate the CGPA if you have 9 in Science, 7 in English, 9 in Hindi, 8 in Social Science, and 10 in Mathematics. Also, calculate the overall percentage and percentage in each subject.

There are a total of 5 subjects for your class as per the question.

Total grade points earned= 9 + 7 + 9 + 8 + 10 = 43.

CGPA= 43/ 5 = 8.6.

Total percentage= 8.6 x 9.5 = 81.7%

Percentage in each subject:

Name of the Subject CGPA Percentage
Science 9 85.5
Maths 10 95
English 7 66.5
Social Science 8 76
Hindi 9 85.5

CBSE Conversion Certificate

CBSE students are well aware of the marking scheme of the 10th and 12th standards. It is according to the grade points earned in each subject, and the average grade point referred to as CGPA. According to CBSE, grade points are assigned as A1, A2, B1, B2…..

While you are into your exam, you will get a certificate that clearly mentions grade points with the corresponding marks range.

For Example

If your grade point is 10, that means your grade is A1 and marks are between 91-100.

What is the Reason for Multiplying 9.5?

Assigning grade systems and CGPA systems is not an everyday task. CBSE that undergone a complete survey for the same. They took a record of students from the past five years and found that the average marks of the students who have earned a band between 91-100 are 95. This is grade A1 with a grade point of 10. Now, after dividing the average marks by 10, we get 9.5. This is how CBSE used the 9.5 factor to calculate the percentage.

How to Get CGPA from Percentage for Engineering?

Now suppose you are given the percentage of marks obtained. What will be the CGPA earned? To calculate CGPA from percentage, reverse the use of 9.5. Divide 9.5 by percent of marks obtained by you. Suppose your percentage is 94%, then CGPA is 94/ 9.5. The resultant 9.8 is your CGPA.

CGPA to Percentage in Terms of UPSC

The percentage from CGPA is calculated according to its own terms. One such example is CBSE. However, if you submit your final percent obtained if the university asks for the same, you need to submit according to their guidelines. In case you don’t know the calculation system, UPSC has given an overall formula to calculate the percentage. Suppose your undergraduate level CGPA is 9.0, and your university asks you to submit your percentage, then multiply it with 10 to get your percentage. Your percentage will be 90.

What are the Benefits of the CGPA system?

  • CGPA is basically a grade point system. These grade points help in developing good competition among students. The fact is, none obtains specific marks or ranks in their finals. Thus it helps in the good development of the student’s academic mind.
  • Your percentage, according to the CGPA system, will define aggregate marks. CGPA defines your marks in the form of grades.
  • It is easy to work with CGPA, while on the other hand, it is good to go with a percentage. Both the systems are important to understand in every aspect.
  • Some universities consider both the system. Thus, you need to be sure and clarify your doubts, if any, with CGPA and the percentage system. Various universities provide a formula to calculate percentage from CGPA as per their guidelines. If not so, you can multiply it by 10. This is universally accepted.

The grading system is not only limited to CGPA but also about GPA. CGPA is a term used in India, but GPA is recognized in the entire world. GPA is actually the grade points obtained every semester. CGPA is actually the average of all credits earned, marks obtained, and grades obtained. However, if you plan for an abroad study, you need to submit your points according to the universally accepted method. Be prepared to mention your grades in a professional tone. However, if you target any university, you need to understand their calculating policy and mentioned grades accordingly.

Grade Table According to CBSE

It is not the only CGPA mentioned in your final report and additional grades and grade points. You can convert your grade to the corresponding number. The below will help you out:

Marks Grade Grade Points
91-100 A1 10
81-90 A2 9
71-80 B1 8
61-70 B2 7
51-60 C1 6
41-50 C2 5
33-40 D 4
21-32 E1
0-20 E2

The 10 Point Scale

The 10 point Scale is considered the highest marks obtained by a student. Suppose the highest marks obtained are 94, then 94 will be 100%. If a student gets 85 marks in a particular subject, then CGPA is calculated concerning [100/94] / 85 = 85.10. Hence the CGPA will be 8.5 according to the 10 point scale.

CGPA to Percentage According to Indian Universities

Universities want to keep records of the percentage of marks obtained. However, the calculation is different according to their guidelines. Hence students need to refer to their official websites for the same. Here are a few examples from the top universities of India.

Laws of Boolean Algebra

Here, we are providing the basic laws of boolean algebra that assist you when solving the boolean algebra expression.

    • Idempotent Law

A * A = A

A + A = A

    • Associative Law

(A * B) * C = A * (B * C)

(A + B) + C = A + (B + C)

    • Commutative Law

A * B = B * A

A + B = B + A

    • Distributive Law

A * (B + C) = A * B + A * C

A + (B * C) = (A + B) * (A + C)

    • Identity Law

A * 0 = 0 and A * 1 = A

A + 1 = 1 and A + 0 = A

    • Complement Law

A * ~A = 0

A + ~A = 1

    • Involution Law

~(~A) = A

    • DeMorgan’s Law

~(A * B) = ~A + ~B

~(A + B) = ~A * ~B

    • Redundancy Laws


A + (A * B) = A

A * (A + B) = A

(A * B) + (A * ~B) = A

(A + B) * (A + ~B) = A

A + (~A * B) = A + B

A * (~A + B) = A * B


Question: Solve ~(A * B) * (~A + B) * (~B + B)?


Given expression is ~(A * B) * (~A + B) * (~B + B)

By applying Complement law i.e ~B + B=1

=~(A * B) * (~A + B) * 1

Apply Identity law i.e (~A + B) * 1=~A + B

=~(A * B) * (~A + B)

Apply DeMorgan’s law i.e ~(A * B)=(~A + ~B)

=(~A + ~B) * (~A + B)

Distributive Law is ~A + B=B

=(~A + ~B) * B

Complement law says ~B * B=0

=~A + 0

Apply Identity law


~(A * B) * (~A + B) * (~B + B)=~A

Steps to find Area Between Two Curves

Follow the simple guidelines to find the area between two curves and they are along the lines

  • If we have two curves P: y = f(x), Q: y = g(x)
  • Get the intersection points of the curve by substituting one equation values in another one and make that equation has only one variable.
  • Solve that equation and find the points of intersection.
  • Draw a graph for the given curves and point of intersection.
  • Then area will be A = ∫x2x1 [f(x)-g(x)]dx
  • Substitute the values in the above formula.
  • Solve the integration and replace the values to get the result.


Question: Calculate the area of the region bounded by the curves y2 + 4x – y = 0 and the straight line y = x?


Given equations are y2 + 4x – y = 0, y=x

y2 + 4x – y = 0

Add y and subtract y2 on both sides.

y2 + 4x – y + y – y2 = y – y2

4x = y – y2

Divide by 4 on both sides

x = y – y2/4

Using another equation y = x in the equation of the curve will be

y2+4y-y = 0

y2+3y = 0

y(y+3) = 0

y = 0 or -3

Corresponding to the values of y, we get x = 0 or -3. Thus the points of intersection are P(-3,-3) and Q(0,0).

The graph for the system will be:

Area Between Two Curves

From the graph, the curve on the right is f(y) and the curve on the left is g(y).

f(y) = y – y2/4

g(y) = y

The area is A = ∫x2x1 [f(x)-g(x)]dx

A = ∫30 [(y – y2/4)-y]dy

= ∫30 ((-y2-3y)/4)dy

= [ – y3/4*3 – 3/4 * y2/2]30

= – [(0+0) – (- 33/4*3 – 3/4 * 32/2)

= – ( -27/12 + 3/4 * 9/2)

= 27/24

Area as specified by the definite integral is -27/24.

FAQs on Area Between Two Curves Calculator

1. What is the area between two curves?

The area between two curves is calculated by computing the difference between the definite integrals between two functions. In a two dimensional geometry, the area is a quantity that expresses the region occupied by the equations.

2. What is meant by the polar curve?

A polar curve represents a shape whose construction takes place by using the polar coordinate system. They are marked by points that exist a variable distance from the origin or pole.

3. What is the area under the curve?

The area under a curve is present between two points and can be calculated by conducting a definite integral between those two points. To find the area under the curve y = f(x) between x = a and x=b, you must integrate y = f(x) between the limits of a &b.

4. Find out the area of the region enclosed by y = sin x, y = cos x, x = π/2, and the y-axis?

From the given equations

sin x = cos x

At this interval, x = π/4.

The area will be,

A = ∫0π/4 cos x – sin x dx + ∫π/4π/2 sin x – cos x dx

= [sin x + cos x]0π/4 + [-cos x – sin x]π/4π/2

= (sin (π/4) + cos (π/4)) – (sin 0 + cos 0) + (-cos (π/2) – sin (π/2)) – (-cos (π/4) – sin (π/4))

= (√2/2 + √2/2) – (0+1) – (0+1) + (√2/2 + √2/2)

=2√2-2 = 0.828427.

5. Is it possible for the area between two curves to be negative?

No, the area between two curves will never be negative. Because, the area between two curves is not like the area under the curve. Hence, the area between the two curves is always positive.

SGPA to CGPA Conversion Formula, Examples | How to Calculate CGPA from SGPA?

Convert SGPA to CGPA

Marks Calculation is quite an important aspect in college and school life. However, there are several methods to perform the same task of which GPA is the prominent one. Among all these methods one that appears confusing is the conversion from SGPA to CGPA. Though, SGPA and CGPA serve a similar purpose they are calculated differently. Know about the basic difference between SGPA and CGPA, Conversion Formula, Procedure on how to calculate CGPA from SGPA.

SGPA, CGPA, GPA – Definitions

Here, we will find the basic definitions of both SGPA, CGPA. Refer to them and use them during your Marks Calculations as per your requirement.

What is SGPA?

SGPA is known as Sessional Grade Point Average/Semester End Grade Point Average. It is the grade point average we calculate after the end of an academic session such as the year in school or for a semester in college. Let us add Grade Points of all Subjects in an Academic Year and their Average calculated is known as SGPA for that particular year or session.

What is CGPA?

CGPA is abbreviated as Cumulative Grade Point Average. The major difference between CGPA and SGPA is that CGPA is calculated considering the SGPA’s of different semesters in an academic year.

What is GPA?

GPA in simple terms is referred to as Grade Point Average i.e. the average given to a student throughout a semester. It can also be found depending on the different courses students have opted for. We can say that GPA indicates the achievement level of a student so that teachers can assess their performance for a particular period of time.

In Indian Grading System we use a 10 Point GPA Scale and the GPA can be calculated from percentage using the below formula

GPA = Percentage/9.5

In the US GPA Scale of 4.0 is used and to find the GPA simply divide the Percentage by 100 and then multiply with 4.

GPA = (Percentage/100)*4

How to Calculate CGPA from SGPA?

From the definitions of SGPA and CGPA, we can frame CGPA as the collection of SGPA’s calculated at the end of the year. Before, calculating the CGPA you just need to find the average of all subjects in each of the semesters i.e. SGPA. After that, add the SGPA’s of all the Semesters and divide by the number of semesters to obtain the CGPA.

CGPA= (SGPAs of All Semesters in an Academic Year)/Number of Semesters


If a student scored 6 and 8 SGPA in their two semesters, their CGPA would be

Formula to Calculate CGPA = SGPAs of All Semesters in an Academic Year/Number of Semesters

= (SGPA in Semester 1+ SGPA in Semester 2)/Number of Semesters

= (6+8)/2

= 7

Therefore CGPA is 7.

8 CGPA in Percentage is 76%


Go through the below pointers to know the key differences between SGPA, CGPA, and GPA. They are along the lines

  • CGPA is the Cumulative GPA and is obtained by dividing Sum of SGPA’s in all the Semesters by the Number. of Semesters. In Other Words, we can say that CGPA is found for the entire course whereas GPA is for a Semester and SGPA is for a particular session such as a year or so.
  • Grading System differs from college to college. Some of them use GPA while others use CGPA to determine the scholastic abilities of a Student.
  • CGPA and GPA highlights the student’s academic performance for a stipulated period of time. The majority of the institutions prefer GPA over CGPA to provide Admissions to Candidates.
  • CGPA reflects your performance for an entire course so it is a higher one in comparison to GPA and SGPA. One more Prominent Difference is SGPA and CGPA differ on a scale of 0.0 -10.0

How to Calculate SGPA?

After learning the definition of SGPA the next essential step is to learn how to calculate SGPA. Semester Grade Point Average reflects a student’s performance for a stipulated period of time i.e. a semester or so. In order to find out SGPA, you need to consider all the credit points you have obtained in a semester and then divide them with the total number of credit points for that semester. Follow the below steps to learn how to find the SGPA.

  • In the Initial Step Multiply the Credit Point of Each Subject with the Grade Point you have obtained in the Particular Subject.
  • After that Add all the Total Grade Points you have got.
  • Now, divide the sum with the total credit points of the semester to obtain the SGPA.


Let’s say you have three subjects in a semester, and you have scored the following grade points,

Subject 1: 7; Subject 2: 6 and Subject 3: 7

Now, suppose the credit points for these subjects are:

Subject 1: 4; Subject 2: 4; Subject 3: 2


Firstly, multiply the grade points with respective credits

Subject 1 = 7*4 = 28

Subject 2 = 6*4 = 24

Subject 3 = 7*2 = 14

Add all the Grade Points as well as the Credit Points

Grade Points = 28+24+14

= 66

Credit Points = 4+4+2

= 10

To obtain the SGPA simply divide the sum of grade points by the number of credit points

= 66/10

= 6.6


1. Is SGPA and CGPA Same?

No, SGPA and CGPA aren’t the same. SGPA is the Grade Point received for a particular semester whereas CGPA is calculated for the overall Grade Point of a Year.

2. How to Calculate Percentage from CGPA?

You can calculate Percentage from CGPA using the Formula Percentage = CGPA*9.5

3. How is CGPA Calculated from SGPA?

To find the CGPA add the SGPA’s of all the semesters with the number of semesters. The result obtained is the CGPA.
