Odd.

Explanation:

Know that sin(x)=sin(x).

Even function: when f(x)=f(x)
Odd function: when f(x)=f(x)

In this case, f(x)=cscx

f(x)=1sinx

f(x)=1sin(x)

f(x)=1sinx

f(x)=cscx=f(x)

Thus, the function is odd.
graph{csc(x) [-10, 10, -5, 5]}
A property of odd functions is that they have origin symmetry, which means the graph can is symmetrical when reflected over the point (0,0).
