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

     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 "$a\n$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 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 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.
