GXWeb is a new, free browser app which lets you sketch geometric figures and output mathematics.
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 equations 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 for the parameters. Another feature lets you create a locus of a point and gives you the equation of the locus. These features make the app a true mathematical modelling program of interest to Algebra, Geometry and Calculus teachers.
GXWeb uses the full geometry engine and CAS from our Geometry Expressions program.
