A comprehensive scientific calculator app

Yes, your droid comes with a calculator and you might even already have an additional calculator app. However, if you are surviving high school or are in any scientific degree in college, those toy calculators aren't enough. You need to solve quadratic equations and polynomials and vectors and matrixes and draw graphs and all that odd Math stuff we mere mortals can't understand. Perhaps you need to save it all and bring it with you to your PC.

Graphing Calculator is an insanely complete app, thought for helping any need any algebra student may need. It also comes with a smooth interface and a supporting website and email address.

This free version is ad-supported and can't be run offline.

Developer's original description available here
Graphing calculator with algebra. Essential tool for school and college. Replaces bulky and expensive handheld graphing calculators.

Multiple functions on a graph, polar graphs, graphing of implicit functions, values and slopes, roots, extremes, intersections. Algebra: polynomials, polynomial equation solving, matrices, fractions, derivatives, complex numbers and more. Shows results as you type. Use menu to switch between modes.

Free version requires internet connection and contains ads! $5.99 in-app upgrade to PRO. Contact us if you need multiple licenses for a school or organization.

    Great for Math 51 and Math 60. Gives you different forms of the answer. Very useful.

    This is a nearly perfect calculator from simple algebra to complex trigonometric/calc. problems, the only downside is that answers with a radical are put into decimal form instead of radical form, (ex. 2r34) other than that this app is nearly perfect!
