Hi!

Show the approximate location on the unit circle of $\displaystyle P(t)$ for the given value of $\displaystyle t$.

1. $\displaystyle t = -\frac{37\pi}{6} $

2. $\displaystyle t = -\frac{4\pi}{3}$

3. $\displaystyle t = -\frac{7\pi}{4}$

What's the 'process' behind showing where the points are?

I have tried adding/subtracting $\displaystyle 2\pi$ to obtain a point on the unit circle so I can have a general idea. It wasn't concrete.

You can use #1. as an example and I'll do the rest and post.
