Question 849421: Find the terminal point P(x,y) on the unit circle determined by the value of t.
t= pi/2
t=5pi/6
When I look in the book their points are a lot different then what I'm getting. Please help me understand this. Thanks.

Find the terminal point P(x,y) on the unit circle
determined by the value of t.
Note: On the unit circle P(x,y) is (cos(t),sin(t))

If t= pi/2, x = 0, y = 1
----------------------------------------
If t=5pi/6, x = -sqrt(3)/2 ; y = 1/2
