Question

How do you graph the point `R(-7/2, 1050^o)`?

Answer 1

see below

Explanation:

First, find the co-terminal angle for `1050^@`. Note that if you start from the positive x-axis and go counterclockwise (standard position) then you will go around the circle twice and then terminate at `330^@` which is the co-terminal for `1050^@`.

Since r is negative `(-7/2)` it means that we have to plot the point on the opposite ray from `330^@` which is the ray `150^@`.

So halfway between circle number 3 and 4 plot the point on the ray `150^@`.
