${theta|theta != kpi ", for " k " an integer"}$

Note that

$cot theta = cos theta/sin theta$ and

$csc theta = 1/sin theta$ .

Therefore, $theta$ cannot have any value that makes $sin theta = 0$ .

So $theta$ cannot be an integer multiple of $pi$

$theta$ can have any other value

So the domain is ${theta|theta != kpi ", for " k " an integer"}$
