it is a exponential fourier coefficient..
i m lost at how to proceed thence.
question: find exp fourier series for \(D_n=\frac{1}{T}\int_{0}^{T/2}Ae^{-jn\omega t} dt\)
after some deduction,
\(D_n=\frac A {j2\pi n}(1-e^{-jn\pi}) \)
i have the problem how that proceeds to,
\(D_n=\frac A{2\pi n}[1-cos(n\pi)]e^{-jn/2}\)
i would very appreciate someone will guide me...thank u.
