Which of the following represents the domain and range of y = sin x?

I just took the test and got 100%

1: C, Domain:(-infinite,infinite)

       Range: [-1,1]

2: D, Domain: -infinite< x < infinite, x =n pi, where n is an integer

        Range: -infinite < y < infinite

3: A, Domain: -infinite< x < infinite, x = pi/2, where n is an integer

Range: y _< -1 or y _> 1 _< means less than, _> greater than or equal to :)

4: C, y= tan x

   D, y= cot x

These are 100% feel free to mark as brainliest

the answer is 62.8 cubic units

this may not be at all, but i use the same website you're using for school, and if i'm stuck doing one of these i try to look for it on the section.
