Quick Graph – Quick Graph Review

I have used calculators, computers, Excel and several iPad Apps to solve math and engineering problems in my business and recreation, but I would not trade any of them for Quick Graph. It is a lot more than a calculator, it is better and quicker than Excel, and far superior to other iPad math apps. The graphing is excellent, quick, and very accurate. For example, by zooming in on two transcendental equations to find roots, 4 and 5 place numerical accuracy can be obtained by highlighting where the two curves cross. Multiple roots can also be found. You can save the solutions for later reference. I would like to see more functionality for other math problems, perhaps a small calculator pop up for side calculations, and some pop up help with the many keys and functions. A hide/unhide equation button would be nice when too many lines and equations appear on screen that confuse. A library of identities, stored constants, and user defined variables would also be nice, but these things do not alter the value of Quick Graph. Does QG allow substitutions of one equations result into another? Fabulous App.....Good job.
