Im just looking through examples of finding the fourier coefficients.(adsbygoogle = window.adsbygoogle || []).push({});

in one particular example bn is found to be = (-1/npi) (cosnpi - cos 0)

then it says this is 0 when n is even

and 2/npi when n is odd

are we just substituting values of n e.g. 1,2,3..... to find this result?

i apologise if i am doing something stupid with my calculation but when i put even numbers in place of n i do not get 0 as it states i should?
