Given:
(a) Find an angle between 0 and 2π that is coterminal with 10π/3
The given angle (10π/3) > 2π
So, we will subtract 2π to get the coterminal angle
So, the answer will be 4π/3
============================================================
(b) Find an angle between 0 and 360 that is coterminal with -240
The given angle is a negative value of the angle, to get the positive value add 360
So,
![-240\operatorname{\degree}=-240\operatorname{\degree}+360\degree=120\operatorname{\degree}]()
So, the answer will be 120°
