Graph is an open source application used to draw mathematical graphs in a coordinate system. Anyone who wants to draw graphs of functions will find this program useful. The program makes it very easy to visualize a function and paste it into another program. It is also possible to do some mathematical calculations on the functions.
It includes a huge number of predefined functions, but new ones can be added. Tangents, normals, and derivatives can be drawn. Users can add relations and set constraints. The program can calculate the length or area of a selected function, or determine its first and second derivatives. From a cosmetic point of view, users can freely adjust axes, figure width and color, and shading.

MathType is a powerful interactive equation editor for Windows and Macintosh that lets you create mathematical notation for word processing, web pages, desktop publishing, presentations, elearning, and for TeX, LaTeX, and MathML documents.
The design is simple and straightforward, and navigating the app's features is simple to master. This app performed very satisfactorily during our tests. Building an equation in the editing pane was a simple matter, by clicking buttons to select a symbol or using the Insert Symbol command. Copying and pasting from the editing pane into another app was a snap. MathType offers a number of formatting options to suit a variety of equation types. We appreciated the range of options available for customizing the app through the Preferences dialog box, and most users should be satisfied by this list of options.
