# IMCSCH function: Description, Usage, Syntax, Examples and Explanation

## What is IMCSCH function in Excel?

IMCSCH function is one of Engineering functions in Microsoft Excel that returns the hyperbolic cosecant of a complex number in x+yi or x+yj text format.

## Syntax of IMCSCH function

IMCSCH(inumber)

The IMCSCH function syntax has the following arguments.

**Inumber:**A complex number for which you want the hyperbolic cosecant.

## IMCSCH formula explanation

- Use COMPLEX to convert real and imaginary coefficients into a complex number.
- If inumber is a value that is not in the x+yi or x+yj text format, IMCSCH returns the #NUM! error value.
- If inumber is a logical value, IMCSCH returns the #VALUE! error value.
