Im just looking through examples of finding the Fourier coefficients.
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?
