What i did wrong in this? trigonometry : (it saysfins the exact values of the six trigonometric functions for the given angles by following the steps below.

i) the least positive coterminal angle can be found by subtracting 2pi from your original angle.  We subtract 2pi because 11pi/3 is larger than 2pi.

So: 11pi/3 - 2pi = 11pi/3 - 6pi/3 = 5pi/3 or

ii) The reference angle is the smallest angle you can make with the x-axis.  Since 5pi/3 is in Quadrant IV, the reference angle is found by:

2pi - 5pi/3 = 6pi/3 - 5pi/3 = pi/3 or

iii) 5pi/3 or 300 degrees is found in Quadrant IV.

the answers are in the images, i received 100% on this assignment. hope this !
