Question

Which function has a period of л?

A. y = cos x
B. y = csc x
C. y = cot x
D. y = sin x​

Answer 1

C - the graphs for tan(x) and cot(x) have an asymptote every oí units before repeating

Answer 2

C. y = cot(x)

Explanation:

You want to identify the trig function with a period of π.

Period

The trig functions sine and cosine, and their inverses cosecant and secant, have a period of 2π.

The trig function tangent, and its inverse cotangent, have a period of π.

The function with a period of π is y = cot(x), choice C.
