Math::Trig
==========

Provides subroutines for coverting between degrees, radians, and gradians; converting between different coordinate systems (cartesian, spherical, cylindrical); and great circle formulas.

Also provides versions of the common trigonemetric functions that take or return their arguments in degrees:

    sind
    cosd
    tand
    asind
    acosd
    atand
    atan2d

There are also some useful constants defined:

    pi2 = pi/2;
    pi4 = pi/4;
    _2pi = pi*2;
    _4pi = pi*4;

SYNOPSIS
--------

    use Math::Trig :ALL; # includes the trig functions

INSTALLATION
------------
