Coordinates

This applet aids to visualize the concept of coordinate and the concept of change of basis in linear algebra.

The red vector is editable by click and drag, and so are the basis vectors.


This is a Java Applet created using GeoGebra from www.geogebra.org - it looks like you don't have Java installed, please go to www.java.com


Observe that not only the orientation of the new base vectors is important, but also the module.

Try to insert two linearly dependent vectors as generators of the base B. You'll get an error message. Why?
