Math::Algebra::Symbols is a Symbolic Algebra in Pure Perl.

SYNOPSIS

Example symbols.pl
#!perl -w -I..

use Math::Algebra::Symbols hyper=>1;
use Test::Simple tests=>5;

($n, $x, $y) = symbols(qw(n x y));

$a += ($x**8 - 1)/($x-1);
$b += sin($x)**2 + cos($x)**2;
$c += (sin($n*$x) + cos($n*$x))->d->d->d->d / (sin($n*$x)+cos($n*$x));
$d = tanh($x+$y) == (tanh($x)+tanh($y))/(1+tanh($x)*tanh($y));
($e,$f) = @{($x**2 eq 5*$x-6) > $x};

print "$an$bn$cn$dn$e,$fn";

ok("$a" eq $x+$x**2+$x**3+$x**4+$x**5+$x**6+$x**7+1);
ok("$b" eq 1);
ok("$c" eq $n**4);
ok("$d" eq 1);
ok("$e,$f" eq 2,3);
