# COSH

Returns the hyperbolic cosine of an angle.

## Synopsis

COSH(number)

### Arguments

number | An expression that resolves to a number that expresses an angle in degrees. |

## Description

The COSH function takes an angle in degrees and returns the ratio of two sides of a right triangle. The ratio is the length of the side adjacent to the angle divided by the length of the hypotenuse. This ratio is in the range of 1 to -1 (inclusive).

## Examples

The following example uses the COSH function to return the hyperbolic cosine of an angle:

Dim MyAngle MyAngle = 1.3; ! Define angle in degrees. PRINT COSH(MyAngle); ! Returns hyperbolic cosine ratio.
