Question

How do you plot the polar coordinate `(4, (-4pi)/3)`?

Answer 1

see below

Explanation:

From the polar axis (positive x-axis) on the polar plane, go down `240^@` or `(4pi)/3`. You will end up on the ray `120^@` or `(2pi)/3`.

Once you get there, find the intersection of the ray `(2pi)/3` and the fourth circle and plot the point on it .
