Hello,

Find the Fourier serie of f(x)=|sin(x)| on the interval (-1,1)

I'm just a little confused, does that mean that I have to integrate from -1 to 1 to find the coefficients ? Because the formula of the coefficients is in terms of the period T, for this function the period is pi. Or do I have to consider it only in -1,1 and take the period T=2 ?

Thanks
