CSC: Returns the cosecant of an angle, defined as `1 / SIN(angle)`.
Summary
Use CSC for reciprocal-sine calculations in radian-based formulas.
Remarks
- Domain: valid for all real angles except where
SIN(angle) = 0. - Radians: input is interpreted in radians.
- Errors: returns
#DIV/0!at or near integer multiples ofPI().
Examples
