Example found on a website...(there were no graphs or explanations as to p or r or q)(adsbygoogle = window.adsbygoogle || []).push({});

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
