the fourier series equation given on wikipedia for a triangular wave is given in attachments .
Can anyone plese explain this result or just give the stepwise procedures .
I know that as A TRIANGULAR wave consists of only odd harmonics in the fourier notation a0 & an will be zero and there will be only bn components but how to derive the expression given.(see attachments)
