Description
 
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.
- Share graph documents with friends or Graphmatica for Mac or Windows via email or iTunes.

SJ_Art, 5 stars:

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.

Alphacodex, 5 stars:

The app is great for my purpose, I need a fast and easy curve-fitting solution. Just enter some points, press "Curve fit" and you'll get a perfect solution. The app has also recently been updated for the new iOS and works great for me now! Tested the newest version on a "new iPad" with iOS 6.0
