The Fourier series can also be written as:
f(x) = Ʃcr*exp(r*2π*i*x/L) where sum if from -∞ to ∞
My book says this at least, but I can't really determine the realitionship between the coefficients of an ordinary Fourier and the complex one. How do you get rid of the i that would appear in front of every sin factor, and how do you overall translate the coefficients cr to ar and br of an ordinary Fourier series?
