Verifying a Power Series Solution for y''-4y=0

Click For Summary
SUMMARY

The discussion focuses on verifying a power series solution for the ordinary differential equation (ODE) y'' - 4y = 0, specifically using the power series y = ∑ (2n * x^n) / n! from n=0. Participants emphasize the necessity of understanding the derivative of x^n to begin the verification process. The conversation highlights the importance of showing an attempt at the solution to avoid being locked out of the discussion.

PREREQUISITES
  • Understanding of power series representation

Homework Statement


substitute the given power series below into ODE y'' -4y=0 to verify it is a solution

Homework Equations


y=∑ 2n xn / n!
n=0

y''-4y=0

The Attempt at a Solution



I have absolutely no idea how start.
 
Physics news on Phys.org
you must know the derivative of ##x^n## by now. that's somewhere you could start.
 
Locked because no attempt was shown.
