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.
- Online help and demo files make getting up to speed a snap.
In summary, a great tool for students and teachers of anything from high-school algebra through college calculus.
Pros and cons of iGraphmatica app for iPhone and iPad
iGraphmatica app good for
The app is great for my purpose, I need a fast and easy curve-fitting solution. Just enter some points, press "Curve fit" and youll 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
This app does everything I need for a high school Applied Math course. Great responsive developer as well.
Some bad moments
This graphing app has more features than others that are available, however, when trying to change the grid it crashes. Id like to be able to change the background of the grid since my son is colourblind and cant see the graphs.
You can plot data points and curves of best fit, which is good.
Itd be better if you could control the scale on the axes, ie for y = sinx the x-axis could be set to increase in increments of 30 degrees.
So far, not worth paying for.
Easy to use app that really opens up visualization of what an equation represents. Lots of options and helps.
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.
I have used it for years. If you only have one, this should be it.
I have used Graphmatica on a PC for years to teach college level mathematics and statistics, and it is a great teaching tool! I am excited to be able to use it now on my IPad because my school is pushing this technology and I know this app is easy and effective for student use in all levels of Statistics and graphing all the way through Calculus.
