# Simple Forms Calculator

There are several reasons to use a symbolic algebra program for
calculations involving differential forms. The antisymmetric multiplication
makes it difficult to get the sign right, for one thing. Another
important use is the amount you will learn about forms if you actually
write such a system.
This is a project in progress and some of this material is missing and
all of it is provisional.
The systems here are written in Mathematica. I would love to have them
ported to Maple, and would be willing to work with any volunteers.
I would like to see how complicated these are in maple.

## Simple Forms Calculator

This one works in any number of dimensions. In fact it tries to work in
an unspecified number of dimensions.

## Tiny Forms Calculator

This one works just with ordinary forms in three dimensional Euclidean
space. This lets you see the guts of such a system without the
complications of pretty printing, high dimensions, and twisted forms.
