Introduction to Geo Gebra :
Geo Gebra is a dynamic mathematics software that joins geometry, algebra and calculus. It is developed for learning and teaching mathematics in schools by Markus Hohenwarter and an international team of programmers.
This software is used for constructing geometric objects such as points, vectors, segments, lines, polygons, conic sections, and functions that can be changed dynamically. These objects can be entered and modified directly on screen or through the command line. Geogebra has the ability to use variables for numbers, vectors and points and find the derivatives and integrals of functions.
