Math::Trig

Defines many trigonometric functions not defined by the core Perl, plus the constant pi and some additional functions for converting angles. For example: 

use Math::Trig; $x = tan(0.9); $halfpi = pi/2;

The following functions are defined. A slash (/) between two functions means the values are aliases.

  • acsc/acosec, asec, acot/acotan
  • Arcus cofunctions of sine, cosine, and tangent
  • acsch/acosech, asech, acoth/acotanh
  • Arcus cofunctions of hyperbolic sine, cosine, and tangent
  • asin, acos, atan
  • Arcus (inverse) functions of sine, cosine, and tangent
  • asinh, acosh, atanh
  • Arcus functions of hyperbolic sine, cosine, and tangent
  • atan2(y x)
