# How to Use CSCH Function

The CSCH function is to return the hyperbolic cosecant of an angle specified in radian.

Formula:

=CSCH(number)

Explanations:

– "Number" is required, which is the angle in radians you want the hyperbolic cosecant.

Cautions:

– The number is the angle in radians. If the angle is in degrees, use PI()/180 or the RADIANS function to convert the angle to radians.

– CSCH function applies to Excel 2011 and above.

Example:

Step 1: Convert degrees into radians using PI()/180 or the RADIANS function;

Step 2: Use the CSCH Function with the degrees in radians.
