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) Principal value of arc tangent of y/x
csc/cosec, sec, cot/cotan Cofunctions of sine, cosine, and tangent
csch/cosech, sech, coth/cotanh Cofunctions of hyperbolic sine, cosine, and tangent
deg2rad Degrees to radians
deg2grad Degrees to gradians
grad2deg Gradians to degrees
grad2rad Gradians to radians
pi
