# IMCSCH function

The IMCSCH function returns the hyperbolic cosecant of the given complex number.  For example, a given complex number "x+yi" returns "csch(x+yi)."

## Parts of an IMCSCH function

`IMCSCH(number) `

 Part Description Notes `number` The complex number for which you want the hyperbolic cosecant. This can be either the result of the COMPLEX function, a real number interpreted as a complex number with imaginary parts equal to 0, or a string in the format “x+yi” where x and y are numeric.

## Sample formulas

`IMCSCH(COMPLEX(4,6))`

`IMCSCH(4)`

`IMCSCH("2+3i")`

## Notes

The `IMCSCH` function returns an error if the given number isn't a valid complex number.
