1. Determine the quadrant in which the terminal side of the angle is found and find the corresponding reference angle.

theta = 4

I know how to find the terminal side when theta has pi in it (for example: 4pi/3), but I don't understand what just "4" means. 4 pi?

2. Find an angle between 0 and 2pi that is coterminal with the given angle.

11pi/7

How do I find an angle coterminal to 11pi/7 when that angle itself is already between 0 and 2pi?
