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.
Note: cos(-x)=cos(x), cos is an even function
Note: cos(x)=cos(x-2kπ) where k is an integer.
sin(x) = sqrt(1-cos²(x))
tan(x) = sin(x)/cos(x)
