Question

How do you determine if `y=cotx` is an even or odd function?

Answer 1

See below

Explanation:

A function is even if `f(-x) = f(x)`. For example, `cos(-pi)=cospi`, so `y=cosx` is an even function.

A function is odd if `f(-x)=-f(x)`. For example, `sin(-pi)=-sinpi`, so `y=sinx` is an odd function.
