# COSH

### Definition of COSH

Returns the hyperbolic cosine of any real number.

### Sample Usage

`COSH(A2)`

`COSH(1)`

### Syntax

`COSH(value)`

`value`

- Any real value to calculate the hyperbolic cosine of.

### Notes

- Excellentable does not support imaginary or complex numbers, so these are not valid inputs or outputs from hyperbolic functions.
