Find the sinx if cotx is undefined and π/2≤x≤3π/2
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
cot(x) is undefined if and only if sin(x)=0.
Do you ask for sin(x) ? - The answer is: sin(x) = 0.
The last info in the post is irrelevant.
It becomes relevant if you ask about x.
But you didn't ask about x.
