Permitted values |
|---|---|---|
value |
The angle for which the hyperbolic cosecant need to be calculated |
Any real number other than 0. Can be specified as a number, formula, function, or cell reference |
Examples of use
Calculation of hyperbolic cosecant for 1
=CSCH(1)
Result: approximately 0.8509.
Calculation of hyperbolic cosecant for −1
=CSCH(-1)
Result: approximately −0.8509.
Attempt to calculate the hyperbolic cosecant for 0
=CSCH(0)
The expression will return the #DIV/0! error, since the hyperbolic cosecant is undefined for zero.
Notes
It is important to remember that the CSCH function is undefined for x=0, since the hyperbolic cosecant tends to infinity at this point.
