# Fourier coefficients

Fourier coefficients / b1, b2, b3, b4, b5... b11.

--------------------------------------------------------------------------------

I have an output of an electronic device (full wave rectifier) that gives a sine wave with the negative part transposed symmetric to xx so that the function is always positive. I have to find the fourier coefficients of that function from n= 1 -> n=11, namely>b1, b2, b3, b4, b5... b11.

What are the exact decimal terms of the b1, b2, b3, b4, b5... b11 coefficients?

The wave is shown in the attachment .gif file.
