Thanks very much for these .. I will study/play with them, and hopefully my function falls under 'simple case' .. thanks again.

It may be a poor question then .. my frame of reference is the typical fourier series for periodic functions found on-line (square, triangle, saw), which all seem to reduce to nice clean equations for the nth coefficient. I didn't realize most would not behave so nicely .. though, I don't feel so bad now for scratching my head about the more complex function for which I was trying to generate a series .. smile. Thanks for the input/answer.

Is there a way to recover the general formula for a fourier series? That is, f.fourier_series_sine_coefficient(9,pi) will give me the 9th sine coefficient, but I'd like to know more generally how I can construct the Nth sine coefficient.

I'm doing some complicated (to me) fourier series, and I'm having trouble figuring out the formula for the Nth.

Thanks for any help.
