Problem

 

Solution

 This below show how to do this. From definition of fourier coefficients, we calculate the coefficients for up to some fixed n. Then plot f[x] and the approximated f[x] and compare the two functions on the same plot.  I also show Fouries approximation for 2 other functions, the sawtooth and the square function.

 a[n] and b[n] Fourier coefficients for n up to  10
