1. ## Find Functions

If the inital side of is along the positive x-axis and the terminal side includes the point ) find each of the following functions of :
(a) ?
(b) ?
(c) ?

2. Look below

3. On a unit circle $x^2 + y^2 = 1$, $P(x,y)$ is defined to be $P(\cos{\theta},\sin{\theta})$.

Recall that $\tan{\theta}= \frac{\sin{\theta}}{\cos{\theta}}$ and $\sec{\theta} = \frac{1}{\cos{\theta}}$.

EDIT: I didn't see your post Jameson. I guess I should refresh before I post next time.
