Quick Graph is a powerful, high quality, graphic calculator that takes full advantage of the multitouch display and the powerful graphic capabilities of the iPad and iPhone, both in 2D and 3D. A simple, yet intuitive interface that makes it easy to enter and/or edit equations and visualize them in mathematical notation.
[Top ten] Excellent tool
If you know math and had enough of the false pretense interfaces, this is the application for you. Being able to visualize surfaces at various contrast levels helps with relative orientations and to identify their intersections. The 3D perspective from any angle is perfectly realistic. This app was created by people that really know Math and what is involved in solving math problems.
