Question 619102: how would find a negative co-terminal angle of 15pi/4
pi/4 would take you one fourth around the circle to the left.
It takes 2 pi to get around the circle once going clockwise. 15/4 = 3+ 3/4 pi which would be 2 pi + 1 + 3/4 pi.
2 pi equals one complete circle and another 3/4 , so you would end up with your terminal side in Quadrant I and co terminal angle would be 45 degrees Answer by mathgranny(13) (Show Source):
