Question

Find the measures of two angles, one positive and one negative, that are coterminal with pi/2.

Answer 1

so any angle that is coterminal is equal to the angle plus or minus an integer multiple of 2 * pi radians (or 360 degrees).

So, pi/2 + 2pi (5pi/2) and pi/2 - 2pi (-3pi/2) are both coterminal with pi/2

Answer 2

ohh thank you very much! :)

Answer 3

No problem!
