Answer:
c)
Step-by-step explanation:
To solve this, remember some properties of trigonometric functions.
Let . Then, by definition of inverse function, . Multiply by -1 to both sides of this equation to get .
Note that because sine is an odd function and cosine is an even function. Then . Take the inverse tangent in both sides to get .
Using the previous equations, we obtain:
