Second Order Differential Equation is represented as d^2y/dx^2=f”’(x)=y’’. Have a look at the following steps and use them while solving the second order differential equation.
- Take any equation with second order differential equation
- Let us assume dy/dx as an variable r
- Substitute the variable r in the given equation
- It will form a binomial equation
- Solve the equation and find its factors
- Find the value of y
Example:
Question: Solve d^2y/dx^2-10dy/dx+25y=0?
Answer:
Given equation is
d2y/dx2-10dy/dx+25y=0
Let us take y=erx then
dy/dx=rerx
d2y/dx2=r2erx
Substitute these values in the equation
r2erx-10rerx+25erx=0
erx (r2-10r+25)=0
r2-10r+25=0
r2-5r-5r+25=0
r(r-5)-5(r-5)=0
(r-5)(r-5)=0
r=5
So, we can say that y=e5x
dy/dx=5e5x
d2y/dx2=25e5x
So,
d2y/dx2-10dy/dx+25y
=25e5x-10*5e5x+25e5x
=25e5x-50e5x+25e5x
=0
So, in this case our solution is
y=Ae5x+Bxe5x
