GeoGebra - Geometry, Algebra and Calculus Freeware

GeoGebra is a free and multi-platform dynamic mathematics software for schools that joins geometry, algebra and calculus. GeoGebra is written in Java. On the one hand, GeoGebra is a dynamic geometry system. You can do constructions with points, vectors, segments, lines, conic sections as well as functions and change them dynamically afterwards.

On the other hand, equations and coordinates can be entered directly. Thus, GeoGebra has the ability to deal with variables for numbers, vectors and points, finds derivatives and integrals of functions and offers commands like Root or Extremum.

These two views are characteristic of GeoGebra: an expression in the algebra window corresponds to an object in the geometry window and vice versa.

GeoGebra can also be used to create dynamic worksheets.It runs in many languages, including English, French, German, Portuguese and Italian.

Canadian Tax Calculator 3.4

"Calculates Canadian sales taxes: GST HST and PST."
Edit By BS Editor: Calculates Canadian sales taxes: GST HST and PST.

price. It als works in Reverse given the
final price working backwards to get the taxes and base
price. In other words it will tell you the sticker
price to make something come out even after taxes are added.

The distributed version is absolutely identical to the
registered version, and includes Java source and sample
HTML. You may use the code freely in your own programs. You
don't need to register multiple copies.

To install, Extract the zip download with WinZip, available from
http://www.winzip.com (or Similar unzip utility) into any
directory you please, often C:\ -- ticking off the (user
folder names) option. To run as an application, type:

java -jar C:\com\mindprod\canadiantax\canadiantax.jar

adjusting as necessary to account for where the jar file is.

You can run the program without installing it as an Applet at
