Description

It is a powerful, high-quality graphing calculator that takes full advantage of the multitouch display and the powerful graphing capabilities of the iPad and iPhone, both in 2D and 3D.

"The app you need to survive the next semester."
-- Gizmodo

A simple yet intuitive interface makes it easy to enter and/or edit equations and visualize them in mathematical notation.

It's capable of displaying explicit and implicit (opt) equations as well as inequalities (opt) in both 2D and 3D, in all standard coordinate systems: cartesian, polar, spherical, and cylindrical, all with fantastic speed and beautiful results, which can be copied, emailed or saved to the photo library.

It also includes an evaluation feature to evaluate equations at specific points and a library where you can store commonly used equations.

Up to 6 equations can be visualized simultaneously in both 2D and 3D modes; this limitation can be removed by purchasing the advanced feature set.

Features:
- Enhanced 2D - 3D plotting mode for great hi-res graphics.
- Adaptive 2D algorithms.
- Hyperbolic and Inverse functions.
- Functions such as Min, Max, if.
- Configurable axis decimal / π
- Independent 2D zoom
- Support for cartesian, polar, cylindrical, and spherical coordinate systems.
- Interactive expression evaluation.
- Library for commonly used equations.
- Swipe to delete equations from the equation list.
- Save to photo library.
- Copy to clipboard.
- Turn graphs on/off
- Drag to rotate - move.

The advanced feature set gives you access to:
- External screen support
- 2D tracing.
- 2D and 3D implicit graphs.
- 2D and 3D inequalities.
- Roots and Intersections (2D)
- Value Table
- More features to come!

What’s New

Version 3.0

Better, faster, more powerful. We've cleaned up behind the curtains to make your Calculator even better.

It's been a long time since the previous update; during this time, we were rebuilding the Calculator from scratch to make sure we resolved the issues you were having and took full advantage of the new technologies we have at our disposal today.

- We have made it easier to write equations
- Improved the control bar to make the interface even more straightforward.
- Created a visualization system that allows for greater detail and precision when graphing.

Wonderful!

If you’re taking any math course, this is a powerful tool to help visualize what you’re working with. I’ve used this since Algebra I and I’ve always wondered what the point of the 3D graph was and how to use it. Now I’m in Multivariable Calculus in college and I use the 3D graphed regularly. This has helped me visualize and understand tangent planes, and 3D functions. I wish it could show points of intersection on a 3D graph (maybe it does but I haven’t figured it out yet) but it does more than a lot of other calculators do in a more elegant way. I love this app, and I recommend it to anyone pursuing math, engineering, or even the high school student looking for a fast, cheap, and simple graphing calculator

Outstanding. Thank you for this app.

Concise, simple, efficient, professional. Does the hard work to minute detail. If one uses math daily and had enough of the false pretense interfaces, this is their Math App. Being able to visualize surfaces at various contrast levels helps with relative orientations and identifying their intersections. The 3D perspective from any angle is accurate. This app was created by highly professional Math aficionados. The community is in debt !

Great graphing program!

The app is much quicker than graphing on a TI 84 or a TI 89. One can change the size of the graph effortlessly and choose the color for each of the graphs. One can graph algebra equations, trigonometric, exponential and logarithmic problems easily. I’m using the app frequently for pre-Calc and I highly recommend it. The iPad version is much larger and the graphs are more beautiful!
