Question

Give positive and negative coterminal angles for the following:

450°
4pi/9
16pi/52

Answer 1

@goformit100 Any ideas?

Answer 2

Going a full turn around a circle is 360 degrees or \(2 \pi \) radians.
Anytime you add or subtract a multiple of 360 degrees you get a coterminal side.
In radians, any time you add or subtract a multiple of \(2 \pi \) you get a coterminal side.
