Math::Algebra::Symbols
Symbolic Algebra using Perl.
Copyright Philip R Brenan, 2004
This package supplies a set of functions and operators to manipulate
Perl expressions algebraically:
use Math::Algebra::Symbols hyper=>1;
my ($n, $x, $y) = symbols(qw(n x y));
my $a += ($x**8 - 1)/($x-1);
my $b += sin($x)**2 + cos($x)**2;
my $c += (sin($n*$x) + cos($n*$x))->d->d->d->d / (sin($n*$x)+cos($n*$x));
my $d = tanh($x+$y) == (tanh($x)+tanh($y))/(1+tanh($x)*tanh($y));
my ($e,$f) = @{($x**2 eq 5*$x-6) > $x};
print "$a\n$b\n$c\n$d\n$e,$f\n";
# $x+$x**2+$x**3+$x**4+$x**5+$x**6+$x**7+1
# 1
# $n**4
# 1
# 2,3

Following the excellent work done by Steffen Müller (CPAN Author:
SMUELLER), I believe that we should try to capture all known Mathematics
symbolically in Perl. Indeed, can you say that you know any Mathematics
at all if you cannot explain it in Perl?
Help with this project would be appreciated.
