GeoGebra
GeoGebra is an opensource, multi-platform dynamic
mathematics software for learning and teaching.
Specifically, this application is dynamic mathematics
software for all levels of
education. It joins arithmetic, geometry, algebra and
calculus. It also provides multiple representations of objects in its
graphics, algebra, and spreadsheet views that are all dynamically
linked.
Constructions can be made with points, vectors, segments,
lines,
polygons, conic sections, and functions. All of the constructions can
be changed
dynamically. Elements can be entered and modified directly
on screen, or through the command line. GeoGebra can use
variables for numbers, vectors and points, find derivatives and
integrals of functions and has a full complement of commands like Root
or Extremum.
Teachers can also use GeoGebra to make conjectures and prove
geometric theorems.

Features include:
- Views:
- Algebra
- Spreadsheet
- Auxiliary Objects
- Horizontal splitting
- Tool creation
- The Graphics View shows the graphical
representation of mathematical
objects (e. g., points, vectors, segments, polygons, functions, curves,
straight
lines, conic sections). Whenever the mouse is moved over one of these
objects a
description appears as a roll-over text and the object is highlighted
