Asking for a friend: With the use of Fourier series, I'm trying to solve an ODE of the form L*y'' + R*y' + y/C = r(x), where r(x) = 1 - x^2 for |x| <= 1, i.e. has a period of 2. To do so I need to represent 1 - x^2 as a Fourier series. In doing so I have to integrate e^(-n * i * pi * x), but I've reached a stumbling block. [more inside]

Quick help needed for my rusty calculus. Regarding algebraic functions, are the terms "no limit" and "limit does not exist" synonymous?

I remember reading an anecdote about Feynman, written by Feynman either in Surely, You're Joking or What Do You Care What Other People Think. He was describing how in his undergraduate years people were really impressed by his ability to do integrals, all because he knew this integration technique that wasn't taught very often. What was that technique?
