How are the coefficients of the Fourier series modified for a function with a period 2πT?
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
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!
