## anonymous 5 years ago Help! The unit of a circle. I missed this class lesson so I need to understand.-precalc find the terminal point P(x,y) on the unit circle given value t= 5(pie)/3

$-1/2,\sqrt{3}/2$

2. anonymous

how did you get that though?

3. anonymous

made another typo$1/2,- \sqrt{3}/2$

4. anonymous

made another typo$1/2,- \sqrt{3}/2$

5. anonymous

counted one pi/3 + 2 pi /3 + ... + 5 pi /3 and then used the reference angle pi/3 and used the appropiate 4 quadrant angle

6. anonymous

did you get that?

7. anonymous

$2\pi - 5\pi/3 =\pi/3$ but you are in the 4th quadrant so you must attach the appropiate signs. Is this making any sense to you?

8. anonymous

yes

Fabulous! Don't miss any more classes!
