Homework Statement
Hello. I need help with orthogonality of the Fourier series coefficients. I know you can use the dirac delta function, (or the kronecker function) in the orthogonality relationship. I want to try and see the derivation using complex form rather than sines and cosines.
Homework Equations
proof of
[itex]\frac{1}{T}\int^T_0 e^{inw_0t}e^{-imw_0t} dt = \delta_{m}{n}[/itex]
The Attempt at a Solution
Basically I haven't got very far, do not know where to start in this proof. any help would be appreciated?
thanks
