• Optimized algorithms allow scrolling and zooming of all graphs in real time. • Find intersections and other critical points for 2D graphs. • Choice of cartesian or polar axis for 2D graphs. • Draw implicitly defined equations e.g. x²+y²=25. • Draw graphs of equations with cartesian, polar, spherical, cylindrical or parametric variables. • Draw graphs of functions of a complex variable, showing the real and imaginary outputs on separate axis. • Choose between real/imaginary or modulus/argument output for complex graphs. • Save images of the graphs to the phone's gallery for use in projects, presentations, etc. • All the graphs' colors are customizable.
