Description

   The trigonometric and hyperbolic functions displayed in this section
   overload the names of the C library floating point trigonometric and
   hyperbolic functions.

   These functions perform complex class calculations using, in part, the C
   library math and trigonometric functions. As such, error handling for the
   routines is through the matherr function. This function may be overridden
   to provide user defined exception handling.

   In the following a and z are variables of type complex.

   a = sin(z)      Returns the sine of z.
   a = cos(z)      Returns the cosine of z.
   a = tan(z)      Returns the tangent of z.
   a = sinh(z)     Returns the hyperbolic sine of z.
   a = cosh(z)     Returns the hyperbolic cosine of z.
   a = tanh(z)     Returns the hyperbolic tangent of z.
   a = asin(z)     Returns the arcsin of z.
   a = acos(z      Returns the arccos of z.
   a = atan(z)     Returns the arctangent of z.
   a = asinh(z)    Returns the hyperbolic arcsin of z.
   a = atanh(z)    Returns the hyperbolic arctangent of z.
