## COSH Hyperbolic Cosine Function

Section: Mathematical Functions

### Usage

Computes the hyperbolic cosine of the argument. The syntax for its use isy = cosh(x)

### Function Internals

The`cosh`

function is computed from the formula

For `x`

complex, it follows that

### Examples

Here is a simple plot of the hyperbolic cosine function--> x = linspace(-5,5); --> plot(x,cosh(x)); grid('on');
