I dont even know what this question is even asking me, and I have no clue where to begin.
Please help!! :(

The question is:

The Fourier Series is a series representation of a peridoic function in terms of sines and cosines. The Fourier series representation of the function

f(x)= {1 0{-1 -pi
is

(4/pi)*((sin(x)/1) + (sin(3x)/3) + (sin(5x)/5) + (sin(7x)/7) +...)

Plot on the same graph the function f(x) and its series representation, using the four terms shown.
