Identify the point (x, y) on the unit circle that corresponds to t = 11π/6

Question

( ? , ? )

Answer 1

pi=180 so then 11(180)/6=330 degrees which corresponds to 30 degrees and since the (x,y) coordinate can be found by (cos(x), sin(x)) where x is the angle in question which is 30. So then cos(30)=sqrt(3)/2 and sin(30)=sqrt(1)/2 or just 1.2 and since the angle of 330 is found in the 4th quadrant the x coordinate is positive and the y-coordinate is negative so then (sqrt(3)/2,-1/2) is the coordinate of 11pi/6/
