Question

How do you plot the polar coordinate `(-2, -45^o)`?

Answer 1

see below

Explanation:

From the polar axis (positive x-axis) go down `45^@`. You will end up on the ray `315^@`.

The -2 means that you are going to plot the point on the opposite ray from `315^@`which is `135^@`. So plot the point at the intersection of the 2nd circle and the ray `135^@`.
