Example found on a website...(there were no graphs or explanations as to p or r or q)
Reverse engineering the question from the answer, I found p to be 180.

A vector that has length 10 makes an angle of p/6 with the x-axis. Find its components.
Solution:
x = r cos q, y = r sin q
So that
x = (10)(/ 2), y = 10 (1/2) = 5
We can write the vector as
5 i + 5j
