Question

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

Answer 1

see below

Explanation:

From the polar axis (positive x-axis) go down `60^@` or `pi/3`. You will end up on the ray `300^@` or `(5pi)/3`.

The -3 means that you are going to plot the point on the opposite ray to `(5pi)/3` which is `(2pi)/3`. So plot the point on the 3rd circle and the ray `(2pi)/3`.
