NAME
Math::Symbolic::AuxFunctions - Auxiliary functions for Math::Symbolic hierarchy
SYNOPSIS
use Math::Symbolic::AuxFunctions;
Math::Symbolic::AuxFunctions::acos($x);
# etcDESCRIPTION
This module contains implementations of some auxiliary functions that are used within the Math::Symbolic hierarchy of modules. In particular, this module holds all trigonometric functions used for numeric evaluation of trees by Math::Symbolic::Operator.
EXPORT
None. On purpose. If I wished this module would pollute others' namespaces, I'd have put the functions right where they're used.
TRIGONOMETRIC FUNCTIONS
tan
Computes the tangent sin(x) / cos(x).
cot
Computes the cotangent cos(x) / sin(x).
asin
Computes the arc sine asin(z) = -i log(iz + sqrt(1-z*z)). Above formula is for complex numbers.
acos
Computes the arc cosine acos(z) = -i log(z + sqrt(z*z-1)). Above formula is for complex numbers.
atan
Computes the arc tangent atan(z) = i/2 log((i+z) / (i-z)). Above formula is for complex numbers.
acot
Computes the arc cotangent ( atan( 1 / x ) ).
asinh
Computes the arc hyperbolic sine asinh(z) = log(z + sqrt(z*z+1))
acosh
Computes the arc hyperbolic cosine acosh(z) = log(z + sqrt(z*z-1)).
