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)
-
