GXWeb, a free mathematical modeling program, combines sketch-based drawing tools and symbolic measurements to extract algebra from a geometric model, solve the algebra and explore the solution. Engage students in inquiry and discovery activities with a rich environment for interactive exploration of mathematical concepts ranging from Algebra and Trigonometry through Calculus.

The combination of sketch-based drawing tools and symbolic measurement capability uniquely builds the bridge between Geometry and Algebra. This is done by drawing a sketch, entering lengths, angles and other constraints, either as numbers or variables or a combination and then discovering measurements, either numeric or as algebraic or trigonometric expressions based on input variables.

If you sketch a function in GXWeb, the program will try to identify what kind of function it is and add an equation with unknown parameters. It will then find suitable values of the parameters. Another feature lets you create a locus of a point and gives you the equation of the locus. Mathematics generated by GXWeb can readily be copied into apps such as Desmos for graphing and Wolfram Alpha for algebraic manipulation. These features make the app a true mathematical modeling program of interest to Algebra, Geometry and Calculus teachers.

GXWeb uses the full geometry engine and CAS from our Geometry Expressions program.
