# Solving a second order differential equation using Fourier s

Please see the attached file for the fully formatted problems.

Consider the ODE

y" - a^2 * y = H(x-Pi/2)

y(0)=y(Pi)=0

0<x<Pi

Where H is the step function.

solve for y using Fourier series

The Fourier series for the step function exhibits the Gibss phenomenon. Will the solution y(x) exhibit it too? explain why or why not.
