If f is integrable on (-\infty, \infty) = E then \lim_{n\rightarrow\infty} \int_E f(x)cos(nx) = 0
it's supposed to be easy if f is a step function & then i can use another problem that was part of the homework, but i can't seem to figure out how that would work.....
(ps- maybe i shouldn't call myself fourier jr if i'm stuck on a problem like this :uhh: )
