CSCH
CSCH: Returns the hyperbolic cosecant of a number, defined as `1 / SINH(x)`.
Summary
CSCH is the reciprocal of SINH where defined.
Remarks
- Domain: valid for all real numbers except
0. - Radians: this function is hyperbolic, so the input is not treated as an angle in radians.
- Errors: returns
#DIV/0!whenSINH(x)is zero (atx = 0).
