README: Math::Algebra::Symbols
   Symbolic Algebra in Pure Perl

   This package supplies a set of functions and operators to manipulate
   Perl expressions algebraically:

   Example symbols.pl

    ($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 "$a\n$b\n$c\n$d\n$e,$f\n";

    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');

INSTALL
   This is alpha code. It is written in pure Perl. It uses the standard
   Perl install mechanism.

   Download from CPAN, untar and:

     perl Makefile.PL
     make
     make test
     make install

   If you are on Windows, use nmake, available at:

   http://download.microsoft.com/download/vc15/Patch/1.52/W95/EN-US/Nmake15
   .exe

   Following the excellent work done by Steffen M�ller (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 Pure Perl?

TO DO
   Help with this project would be appreciated:

   Allow substitution and solution for simple expressions like
   miles/gallon.

   Recognize sin, cos, sinh, cosh etc. in expressions involving exp.

   Sigma,Product

   Taylor series

   Integrals

   Fourier

   Laplace

   Groups

   Sets

   Graphing using Tk.
