Excellent graphing program
Ive been using this program with my students. Its quite simple to use and produces excellent results. Ive had a few small problems with it, and the support people are very responsive and helpful. From my correspondence with them I know that they are planning new features soon to make the program even better.
While its hard to compare applications on the iTunes store (store people please take note!), so I havent made a thorough comparison of the different apps available, this one seems rare in its ability to graph equations that are not defined with y as an explicit function of x (though that does require the very inexpensive add-on feature).
It was already a great program, and the latest updates have made it even better.
You should get this.
