Good evening Tarah! Here is a plot from Desmos for your reference.
From x = 0 to x = 2pi, we only see half of the graph (since the period is 4pi, and the distance from 0 to 2pi is only half this period).
Similarly, we only see half of the graph from x = -2pi to x = 0. From x = 0, we draw the graph backwards to complete half a cycle.
