MathX 1.1 brings Graphical Representation and Sharing Functions Posted 5/23/2014 at 16:07 UTC in iOS by firstname.lastname@example.org | Permalink | Tweet MathX 1.1 brings Graphical Representation on iPhone. Type a function with a smart keyboard (syntax coloring, autocompletion) and MathX will plot you its graph. Graphical Representation can be used from other apps through the x-callback-url protocol. With the new sharing functions, you can now easily export answers and detailed explanations as PDF, image, or even print it. MathX 1.1 also includes a number of improvements for Quadratic Equation, Cubic Equation and others.
