CSCH _ _ _ _ _ _ _ _ _ _ _ _ operator

The cosh operator returns the hyperbolic cosecant of its argument. The derivative of csch and some simple transformations are known to the system.

syntax:

<expression> may be any scalar REDUCE expression, not an array, matrix or vector expression. <simple\_expression> must be a single identifier or begin with a prefix operator name.

examples:

csch b; 

  CSCH(B) 



csch(0); 

  0 



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

  - COTH(X*Y)*CSCH(X*Y)*Y 



int(csch(x),x); 

  INT(CSCH(X),X)

A numeric value is not returned by csch unless the switch rounded is on and its argument evaluates to a number.
