Can someone please explain how the Fourier odd and even extensions could be used to solve differential equations? I understand how to do the extensions, but am not sure when/how to apply that knowledge.

Best ResponseYou've already chosen the best response.0The idea is that Fourier series allow you to decompose a periodic function as well as its derivatives into the sum of sine/cosine parts with meaningful coefficients. That's a really basic way of looking at it so if you need more depth try searching via Google or ask your professor for help.
