Question

Find an angle between 0° and 360° that is coterminal with 474° . (b) find an angle between 0 and 2π that is coterminal with −5π2 .

Answer 1

In order to find a coterminal angel, add or substract 360°.
So,

`474-360=114`
Coterminal angle to -5
`(-5\pi)/(2)+4\pi= (-5\pi+8\pi)/(2)= (3\pi)/(2)`pi/2:
