Fourier Series
I need to find the value of the fourier series of f, F, at pi,
when f = 5x (-pi<=x<0) and 9x(0<=x<pi)
I thought it was just 1/2 (the limit aproaching pi from below +the limit approacing pi from above) i.e 0.5(5pi+9pi)=7pi
but this is wrong, any help?

I also would have thought it was that. See, for example: http://en.wikipedia.org/wiki/Convergence_of_Fourier_series#Convergence_at_a_given_point
Why are you sure it isn't?
