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

Answer:

A

Step-by-step 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: $\frac{-\pi }{2} +\frac{4\pi }{2} =\frac{3\pi }{2}$

Thus, the answer is A.

Answer 2

Answer:  a) 3π/2

Step-by-step explanation:

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

π/2 clockwise lands on 3π/2.
