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!

Polynomial

Features
Read full description

The PolynomialSolver is carefully designed to be a simple and elegant app. Easy to use, easy to understand, simple and effective It solves (finds all the roots) polynomials of any order (any degree). Roots can be real, complex or combination of both. No problem. This app has you covered. To find all the solutions, it uses Aberth Ehrlich algorithm for higher order polynomials. The polynomial is beautifully presented in mathematical format. You can also solve multiple polynomials at once. You can also share the polynomial and its solution. Perform the polynomial division to find the quotient and remainder. This app also plots beautiful graph of the polynomial(s) so that you can visualize the solution in the graph. The graph can be shared with other or it can be saved locally on your device. It automatically saves your hard work locally on your device so you can come back and pick up from where you left off as your great effort will not be lost. This is a perfect app if you are a student learning to solve these kind of equations. There is also a Study page to help you with learning some important polynomial concepts. This is an app for all student groups. From high school to college to university students. Be creative. Enjoy the app!

Verdict

The call

The clearest difference is price: Quick Graph at Free against Polynomial's $1.99. Quick Graph also leads on iOS requirement (9.0 vs 15.1). Polynomial's advantage is in-app purchases (none vs 1) and update cadence (monthly vs every 3 months). On ads and device support there is nothing between them.
