I need to find the fourier series for the function f(x)=x. I have come across trying to find the integral from -pi to pi of -ixSin(nx). How do I go about evaluating this integral when n is infinity? I seem to only be able to find integrals in an integral table where n is an integer, but not when n could be infinity.(adsbygoogle = window.adsbygoogle || []).push({});
