CSC _ _ _ _ _ _ _ _ _ _ _ _ operator

The csc operator returns the cosecant of its argument. The derivative of csc 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:

csc(q)*sin(q); 

  CSC(Q)*SIN(Q) 



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

  -COT(X*Y)*CSC(X*Y)*Y

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