A to Z of Excel Functions: The CSCH Function

Welcome back to our regular A to Z of Excel Functions blog. Today we look at the CSCH function.

The CSCH function

The hyperbolic cosecant function is an old mathematical function. It has a simple definition as the reciprocal to hyperbolic sine function:

It has the following chart properties:

This function returns the hyperbolic cosecant of an angle specified in radians.

The CSCH function employs the following syntax to operate:

The CSCH function has the following arguments:

• number: this is required.

It should be further noted that:

• the absolute value of number must be less than 2^27
• if number is outside its constraints, CSCH returns the #NUM! error value
• if number is a non-numeric value, CSCH returns the #VALUE! error value.

Please see my example below:
