How to cancel out cosine in an equation

WebThe derivation of the Fourier series coefficients is not complete because, as part of our proof, we didn't consider the case when m=0. (Note: we didn't consider this case before because we used the argument that cos ( (m+n)ω0t) has exactly (m+n) complete oscillations in the interval of integration, T).
