    The Fourier Series

    The Fourier Series!! Hi guys, i'm having a bit a trouble helping my daughter with this question on the fourier series approximation: The fourier series for a real, odd function, f(t) can be written as: f(t) = [SUM to infinity, n=1, of]: b[subscipt n] sin(nwt) where f(t=T)=f(t) and...
