Question

What does csc 0 equal?

Answer 1

This value does not exist.

Explanation:

`csc x=1/sin x`

If you try to calculate this for angle `0` you will get an expression with dividing by zero which cannot be calculated, so you cannot calculate cosecans of an angle which is a solution of `sinx=0`, so the cosecans function is undefined for any angle from the set:

`x=kpi` for any `k in ZZ`
