can anyone help me with this question.
Let P be the point on the unit circle U that corresponds to t. Find the coordinates of P and the exact values of the trig functions of t, whenever possible.
(a) pi
(b) 6pi

MathMate
cos(pi)=cos(pi)=1
Note: cos(x)=cos(x), cos is an even function
cos(6π)=cos(0)=1
Note: cos(x)=cos(x2kπ) where k is an integer.
sin(x) = sqrt(1cos²(x))
tan(x) = sin(x)/cos(x)
