Graphing Calculator AR

This app is a port from a program that shipped with the Mac back in the PowerPC days. It was the coolest math program ever back then, and it still is. It is great to have it available on iOS. It is worth many times the price. This app helps math students at all levels visualize functions and graphs in very enlightening ways. We use it frequently in many math classes at the college where I teach. It's capabilities cover every level of math from beginning algebra to multidimensional calculus, complex numbers, and four dimensions, and everything in between. I wish this app had been available when I was a student. The user interface is a model of simple, elegant, and friendly design. It is also beautiful and fun. There are lots of math graphing apps now, but none is both as powerful and easy to use as this one.
