8.147. 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)
- Principal value of arc tangent of y/x
- csc/cosec, sec, cot/cotan
