Question

How do you show that angle 0 degrees has no cosecant and no cotangent?

Answer 1

Both have the sin function in the denominator.

Explanation:

The `sin(0) = 0`, so putting the sin function in the denominator results in division by 0 which is not allowed (undefined). Both `csc(x) and cot(x)` have `sin(x)` in the denominator.
