Quite simple.
180° ÷ 1080°
= 1/6
From 0° to 180° , you draw the first 1/6 of the period.
From 0° to -180°, you draw the last 1/6 of the previous period
It's the same as if you were drawing a graph of y = sinx, but only from -60° to 60°
180° ÷ 1080°
= 1/6
From 0° to 180° , you draw the first 1/6 of the period.
From 0° to -180°, you draw the last 1/6 of the previous period
It's the same as if you were drawing a graph of y = sinx, but only from -60° to 60°
Go to desmos.com to plot if you find it hard to visualise
draw from -540 to 540 on a sketch. Then cut off the graph. copy only the portion from -180 to 180.
