## COTH Hyperbolic Cotangent Function

Section: Mathematical Functions

### Usage

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

### Function Internals

The`coth`

function is computed from the formula

### Examples

Here is a simple plot of the hyperbolic cotangent function--> x1 = -pi+.01:.01:-.01; --> x2 = .01:.01:pi-.01; --> plot(x1,coth(x1),x2,coth(x2)); grid('on');
