This paper uses graphics and animations to illustrate how to construct root and weight diagrams for Lie algebras, and how the root and weight diagrams can be used to identify subalgebras.
A set of articles (and some tutorials) about various tools for developers, including GeoGebra, LiveGraphics3D, Java Sketchpad, PHP, and SVG.
This interactive Geogebra applet allows exploration of a linear transformation in terms of images of a set of points. The Geogebra interface allows dragging of points and vectors to make for versatile explorations of basic linear algebra ideas. Suggested activities are included.
This interactive Geogebra applet allows students to experiment with 2 by 2 matrices and the corresponding geometric transformations of the real plane. A list of student activities is provided.
