1. The problem statement, all variables and given/known data How are the coefficients of the Fourier series modified for a function with a period 2πT? 2. Relevant equations a0 = 1/π ∫π-π f(x) dx an = 1/π ∫π-π f(x) cos(nx) dx bn = 1/π ∫π-π f(x) sin(nx) dx 3. The attempt at a solution I tried letting x= t/T so dx = dt/T and the limits x = ± π, x = ± πT and I was going to plug this into the integrals but I don't think it's right. Any help would be greatly appreciated, thanks!
