COTH Hyperbolic Cotangent Function

Section: Mathematical Functions

Usage

Computes the hyperbolic cotangent of the argument. The syntax for its use is 
   y = 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');
