Question

Which function has zeroes at npi/2, where n is an odd integer. Select two of the following that apply.

Answer 1

A, B

Explanation:

Answer 2

`y=cosx`

`y=cotx`

Explanation:

The trigonometric function;

`y=\cos(x)` has zeroes at
`(n\pi)/(2)` where
`n` is an odd integer.

The trigonometric function;
`y=cot x=(cosx)/(sinx)`. This also has zeroes at
`(n\pi)/(2)` where
`n` is an odd integer.
