Please Help!!

Which function has zeroes at npi, where n is an integer? Select 2.
y=cos x
y=cot x
y=csc x
y=sec x
y=sin x
y=tan x

Answer 1

y=sin x

y=tan x

these are correct....

Answer 2

`y = \sin(x)`

Step-by-step explanation

The trigonometric function that is zero at integral values is the sine function.

That is;

`y = \sin(x)`

has x-intercepts at

`n\pi`

where n is an integer.

In other words, the solution to the equation:

`\sin(x) = 0`

is

`x = n\pi`

where n is an integer.
