Steps to Solve Integration of Function using Taylor Series
Follow these simple steps to solve any function integration using taylor series. These steps are useful for you to get a clear idea on the concept.
- Let us consider any function to find the integration, upper and lower limits of integration.
- Taylor Series formula for a function f is f(x) = f(a) + f'(a)(x-a) + f”(a)/2 (x-a)2 + f”'(a)/3! (x-a)3 + . . . + f(n)(a)/n! (x-a)n
- Where, a is the centre.
- First of all find the derivative of given function and evaluate the derivative at the given point.
- Substitute the obtained values in the above formula to get a polynomial.
- Finally, simplify your polynomial expression to get the final answer.
Question: Calculate Taylor Series of sin(x) up to n=5, centre is 1?
Given function is f(x) = sin(x)
n = 0 to 5, centre = 1
Taylor Series formula is f(x) = f(a) + f1(a)(x-a) + f2(a)/2 (x-a)2 + f3(a)/3! (x-a)3 + . . . + f(n)(a)/n! (x-a)n
By using the above values f(x) will become
f(x) = f(0) + f1(1)(x-1) + f2(2)/2 (x-2)2 + f3(3)/3! (x-1)3 + f4(4)/4! (x-1)4 + f5(5)/5! (x-1)5
So, calculate the derivative and evaluate them at the given point to get the result into the given formula.
f0(x) = f(x) = sin(x)
f(0) = sin(0) = 0
First derivative of f(x) is f1(x) = [f0(x)]’
[f(0)]’ = cos(0) = 1
Second Derivative: f2(x) = [f1(x)]’ = [cos(x)]’ = -sin(x)
Evaluate third derivative (f(0))”’ = -cos(0) = -1
Fourth derivative f4(x) = [f3(x)]’ = [-cos(x)]’ = sin(x)
(f(0))”” = sin(0) = 0
Fifth derivative: f5(x) = [f4(x)]’ = [sin(x)]’ = cos(x)
(f(0))””’ = cos(0) = 1
Substitute these values in the taylor formula
f(x) ≈ 0 + 1 (x-1) + 0/2 (x-2)2 + (-1)/6 (x-1)3 + 0/4! (x-1)4 + 1/5! (x-1)5
≈ (x-1) – 1/6 (x-1)3 + 1/120 (x-1)5
sin(x) ≈ (x-1) – 1/6 (x-1)3 + 1/120 (x-1)5

2. Solve x2+2x with centre 3 using taylor series?
Given fuunction is x2+2x
Taylor Series formula is f(x) = f(a) + f'(a)(x-a) + f”(a)/2 (x-a)2 + f”'(a)/6 (x-a)3
f(3) = (3)2+2(3) = 15
f'(x) = 2x+2
f'(3) = 6+2=8
f”(x) = 2
f”'(x) = 0
Replace the obtained values in the formula
f(x) = 15+ 8(x-3) + 2(x-3)2 + 0(x-3)3
x2+2x = 15 + 8(x-3) + 2(x-3)2
