fourier series

The fourier series of f(x)=x/pi from pi to -pi

Ao = 1?

since the integral would be 1/pi^2 int (x) dx

so 1/pi^2 [x^2/2] from pi to -pi

but the answer says Ao = 0?

[\frac{\pi^2}{2}]-[\frac{(-\pi)^2}{2}] = \frac{\pi^2}{2} - \frac{\pi^2}{2} = 0

OP

Original post by SherlockHolmes

[\frac{\pi^2}{2}]-[\frac{(-\pi)^2}{2}] = \frac{\pi^2}{2} - \frac{\pi^2}{2} = 0

i see, thanks
