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.

Draw functions

Graph can draw normal functions, parameter functions, and polar functions. You can use a lot of built-in functions, e.g. sin, cos, log, etc. You may specify color, width and line style of the graphs, and the graphs may me limited to an interval. It is also possible to show a circle at the ends indicating open or closed interval.

Interact with other programs

You can save the coordinate system with graphs as an image on disk either as a bitmap (bmp), Potable Network Graphics (png) or metafile (emf). You may also copy the coordinate system into another program, e.g. Microsoft Word, either as a normal image or as an OLE object, which may be edited later by double clicking on it.

A lot of options

While still easy to use Graph has a lot of customization possibilities, e.g. fonts, colors, axes style, grids, etc. The axes, which may by normal or logarithmic, can be placed either by entering specific values, or by moving or zooming with the mouse.

Evaluate

Given an x-coordinate Graph will calculate the function value and the first two derivatives for any given function. Alternatively the function may be traced with the mouse. Graph can also fill a table with evaluated function coordinates in a user specified range. Data from the table can easily be copied into another program, e.g. Excel.

Calculate

Graph can help you calculate the area under a function in a given interval and the distance along the curve between two points on the function. The program can also show the first derivative of a function, and create tangents and normal lines to a function at given coordinates.

Point series and trendlines

You can create series of points with different markers, colors and size. Data for a point series can be imported from other programs, e.g. Microsoft Excel. It is possible to create a line of best fit from the data in a point series, either from one of the built-in models or from a user specified model.

Shadings and labels

Graph can insert shadings used to mark an area related to a function. Shadings may be created with different styles and colors in a user specified interval. In addition to the optional legend used to describe each function, a label may be added anywhere in the system. A label can contain text with different fonts, images and objects created in other programs.

Those of us who feel more attracted by books may have enough with the Windows Calculator, but mathematics people definitely need something more. Here's where Derive 6 comes in handy by presenting you with a wide variety of mathematical tools ready to perform almost any kind of maths operation.

The program displays a blank interface where you insert numbers, expressions, symbols and everything you need to create your calculations. The data is entered through a command line and added in consecutive lines on the program's interface. Besides using your keyboard, you can also use the program's buttons to enter certain symbols which may be harder to find on your keyboard configuration. You can then let Derive solve the problem and also get it printed on paper for further study.

All the operators and commands are conveniently categorized into a menu which, together with a comprehensive help system, make the program very complete and easy to use – that is, if you have some basic maths knowledge. Otherwise, you may as well stick to the Windows Calculator!

Equation Grapher is a function plotting and analyzing program. It allows you to draw graphs like y=2x and y=sin(x+10)-cos(x). It is possible to have up to 12 graphs plotted at the same time. Once you have plotted a function, Equation Grapher automatically finds roots, maximum/minimum, intersections etc. You can also calculate and view the integration area. You can change the range of the graph, either by using the built in zoom functions, or by manually typing in the range values. If you like, you can copy the graph window and paste it into your word processor. Of course, it is possible to save your work and continue at another time.

Geometry Expressions is the world's first Interactive Symbolic Geometry System. This means: Geometric figures can be defined by either Symbolic Constraints or numeric locations. Measurements on your drawing are not only presented numerically, but also expressed symbolically as Mathematical Expressions. Your drawing comes to life via parametric, symbolic animation. All the usual constructions are available but also powerful, new symbolic constraints. Geometry Expressions can be used as a stand-alone program or in conjunction with your favorite algebra system via MathML input and output.

Think of Geometry Expressions as a geometry front end for your algebra system. Or think of it as an algebraic extension of your geometry system. Or think of it as a stand alone system that puts the mathematics back in geometry.
