# [SOLVED] terminal point?

#### lsnyder

I have no idea how to do this. Also I just copied and paste the whole problem word-for-word if any one wonders. I am trying to figure it out myself but I'm totally lost. Find the terminal point on the unit circle determined by the given value of :
(a) If , then and ;
(b) If , then and ;
(c) If , then and ;
(d) If , then and ;
(e) If , then and ;
(f) If , then and ;

The terminal point coordinates are the (x,y) coordinates of these values. On your unit circle, start at (1,0), if t is positive, your will move around the unit circle counterclockwise to the value of t. If t is negative, you will move clockwise.

I'll give you the first two and then see if you can work the rest:
a) $$\displaystyle t= \frac{\pi}{2} \rightarrow (0,1)$$
b) $$\displaystyle t = - \frac{\pi}{2} \rightarrow (0,-1)$$

Can you see how this works?
Try the others and come back if you get stuck!
