NAME

Math::Trig - Inverse and hyperbolic trigonemetric Functions

SYNOPSIS

use Math::Trig qw(tan asin acos sinh cosh tanh sech cosech);
$v=tan($x);
$v=asin($x);
$v=acos($x);
$v=sinh($x);
$v=cosh($x);
$v=tanh($x);
$v=sech($x);
$v=cosech($x);

DESCRIPTION

This module exports the missing inverse and hyperbolic trigonemtric functions of real numbers.

tan returns tan of real argument =item asin returns inverse sine of real argument =item acos returns inverse cosine of real argument =item sinh returns hyperbolic sine of real argument =item cosh returns hyperbolic cosine of real argument =item tanh returns hyperbolic tan of real argument =item sech returns hyperbolic secant of real argument =item cosech returns hyperbolic cosecant of real argument

BUGS

Let me know.

I welcome additions such as the inverse trigonemetric functions and the complex versions of the functions to be included in this module.
