Graphmatica is a powerful, easy-to-use, equation plotter with numerical and calculus features:
- Graph Cartesian functions, relations, and inequalities, plus polar, parametric, and ordinary differential equations.
- Data plotting and curve-fitting.
- Up to 999 graphs on screen at once.
- Numerically solve and graphically display tangent lines and integrals.
- Find critical points, solutions to equations, and intersections between Cartesian functions.
- AutoSquare keeps your graphs from getting squashed as you zoom or enable helper panes; or disable it in General Settings so you can scale each axis independently by pinching horizontally or vertically.
- Print your graphs, copy to clipboard or export to Photo Album.

- Online help and demo files make getting up to speed a snap.

Everyone should have it.

I have used it for years. If you only have one, this should be it.

I Really Enjoy Math

My job involves lots of engineering math, but I also enjoy just playing around with graphs. My favorite math toy is now iGraphmatica on my iPad 1, as I can take it along with me for casual equation fun. Not only am I having a good time with it, but my coworkers enjoyed it when I showed it off at lunch. For my usage, the feature set is good and the price is great.
