from fourier transform to fourier series
I really need to find a relationship between the coefficients of the Fourier transform coefficients and those for Fourier series, especially how to find Fourier series coefficients from the Fourier transform coefficients.
The teacher talks about this in class but wants us to find the formula by ourselves.
The formula should be like this:
Where an and bn are the Fourier series coefficients for cosine and sine respectively. Fn are the Fourier transform coefficients.
FinallyX1,X2,X3,X4 are some coefficients( I don't know if they are constant or not)
I could not derive it by myself and did some research with books and online but I have not found something good.
Please can some help me please?
