An angle of 50 degrees in standard position has its terminal side in the first quadrant. What are the coordinates of point P on the unit circle?

Draw a picture of this you will see that you can form a triangle with the radius of the circle being 1. This is the hypotenus of the triangle Using trig, x = cos 50 y = sin 50 P is (x,y) = P is (cos 50,sin 50) = (0.643, 0.766)
