If I divide Ao by two, the fourier expansion sits way too low on the plot. Is Ao supposed to be divided by two or not?

Ao is the DC component... You can check your formula by assuming f(x) = constant = c and integrate over the period. You will probably find that A0 = 2*C so it is necessary that f(x) = A0/2 + .... unless your formula for An has a 2 compensation built in.
