COTH _ _ _ _ _ _ _ _ _ _ _ _ operator

The coth operator returns the hyperbolic cotangent of its argument. The derivative of coth and some simple transformations are known to the system.

syntax:

<expression> may be any scalar REDUCE expression. <simple\_expression > must be a single identifier or begin with a prefix operator name.

examples:

df(coth(x*y),x); 

                2
  - Y*(COTH(X*Y)   - 1) 



coth acoth z; 

  Z

You can write let statements and procedures to add further functionality to coth if you wish. Numerical values of expressions involving coth may also be found by turning on the switch rounded.
