CSC  CSC Trigonometric Cosecant Function


Usage
 
 Computes the csc function for its argument.  The general
 syntax for its use is
 
   y = csc(x)
 
 where x is an n-dimensional array of numerical type.
 Integer types are promoted to the double type prior to
 calculation of the csc function.  Output y is of the
 same size and type as the input x, (unless x is an
 integer, in which case y is a double type).
