Question

Find angle in the normal range (0° to 360°, or 0° to 2pi radians) whose terminal side points in the same direction as terminal side of an angle measuring -pi/2.

​

Answer 1

A

Explanation:

An angle of the measure
`-\pi /2` should have the same measure as an angle measured
`-\pi /2+2\pi` because this is periodic. If we do that, we get the angle:
`(-\pi )/(2) +(4\pi )/(2) =(3\pi )/(2)`

Thus, the answer is A.

Answer 2

Answer: a) 3π/2

Explanation:

Negative means go clockwise around the Unit Circle (starting at 0π).

π/2 clockwise lands on 3π/2.
