Displays graphs of algebraic functions in a variety of forms. These include polar and cartesian co-ordinates, parametric and intrinsic functions.

Displays lines and surfaces defined algebraically in 3D space in many forms, including z=f(x,y), cylindrical polar coordinates, and parametric definitions with one and two parameters. View controls move the viewpoint through 3D space.

Displays the real and imaginary parts of complex functions, or conformal transformations. Bulit-in functions include sine cosine tan sinh cosh exp and Log, and these can be combined to produce a wide range of expressions such as tan(z-2*i) - sin(z*z)
