Maths on your phone

Math4mobile has some interesting maths midlets for use on your Java-based phone. Currently they offer five different midlets for various graphing and learning purposes.

Graph2Go is a special-purpose graphing calculator that operates for given sets of function expressions. Solve2Go supports solving equations and inequalities conjectures based on visual thinking. Conjectures can be refuted or supported by examples provided by the tool, and should be proved using symbolic manipulations on paper. Sketch2Go is a qualitative graphing tool. Graphs are sketched using seven icons representing constant, increasing, and decreasing functions that change at constant, increasing, or decreasing rates. Fit2Go is a linear and quadratic function graphing tool and curve fitter. Students can view a phenomenon, identify variables, conduct experiments and take measurements in order to construct models of the phenomena. Quad2Go is a handy tool for learning about quadrilaterals by generating examples, observing, and experimenting with examples with a view toward forming generalized conjectures.

They include Java emulators so you can test them out in your browser before you decide to download to use on your phone. http://www.math4mobile.com/
