The question is how many harmonic do you need?
So you can plot the function with 2, 3, 4, ... and see how many harmonic will give you a reasonable approximation. You need to decide what is a good approximation first.

First make a plot of
1/pi + (1/2) sin (wt)
then plot another one with more terms

You need to plot the function with the given formula! (Just looking at the formula would not work).
