In the field of mathematical software packages, applications such as Wolfram Research's Mathematica, and Maplesoft's Maple system instantly spring to mind. These are both highly popular, proprietary, commercial, integrated mathematical software environments. Other types of mathematical software packages generally receive much less publicity.
One such area is interactive geometry software, which combines three branches of mathematics: geometry, calculus and algebra. This type of software allows users to create and modify constructions, which are generally in plane geometry. Construction involves building mathematical shapes out of points, lines, conic sections, hyperbola, ellipses, and circles. These diagrams can then be altered and the effects of the mathematical properties of the shapes can be observed.
