Hmm…. Should I spent $50.00 plus on a graphing calculator or $2.99 on an app that does the same thing.

Graphing calculators are expensive, but it’s almost impossible to get your calculus homework done without one. Consider investing in this app instead.

It quickly plots and traces multiple equations on the same graph, using a custom keyboard to speed up entry. It even supports graphing polar and parametric equations and much, much more. Plus, you can take screenshots of your calculator to email graphs to yourself.
