COT _ _ _ _ _ _ _ _ _ _ _ _ operator

cot represents the cotangent of its argument. It takes an arbitrary scalar expression as its argument. The derivative of acot and some simple properties 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:

cot(a)*tan(a); 

  COT(A)*TAN(A)) 


cot(1); 

  COT(1) 


df(cot(2*x),x); 

               2
  - 2*(COT(2*X)   + 1)

Numerical values of expressions involving cot may be foun d by turning on the switch rounded.
