=head1 ABSTRACT

Move the geometric functions (C<atan2>, C<cos>, etc) from the core language
to a loadable module.

=head1 DESCRIPTION

The geometric functions currently included in the core language are of
generally limited and specific value.  This RFC is proposing that all the 
geometric functions should move to a Math::Geometry.pm module and require 
a "use Math::Geomtry;" in order to function in perl 6.

The specific functions that would be covered under this proposal are:

=over

=item

C<atan2>

=item

C<cos>

=item

C<exp>

=item

C<log>

=item

C<sin>

=item

C<sqrt>

=back

Additionally, there are other functions which could be added to this module,
such as:

=over 4

=item

C<acos>

=item

C<asin>

=item

C<tan>

=back

=head1 IMPLEMENTATION

Move code for geometric functions to Math::Geometry.pm, require 
"use Math::Geometry" to enable use of geometric functions.
