Question

If the cos 90° = 0, then the sin 0° =

Answer 1

Remembering that cos is the x values on the unit circle....and at 90 degrees we arrive at the point (0,1) we see that the x value is 0

Remembering that sin is the y values here....and at 0 the point is (1 , 0) we can also see that sin 0 = 0
