Simple Grapher

Simple Grapher is a free educational program, Designed and developed by Brwa Hussen, it allows users to graph mathematics functions, find derivative of functions and other graphing and mathematics tools.^[1][2] It is an application that enables you to create advanced plots and graphs using mathematical functions. The program allows you to graph 2D and 3D drawing for educational purposes and could be a helpful tool for teaching mathematics in middle and high school students. It goes without saying that the app can also be a tool that can help you show off your knowledge and skills.

You can create an image by adding various math equations and points in a definite order. To be more precise, you can incorporate various types of linear equations and values to obtain an accurate straight or curved lines that connect to each other to create a drawing.

The application includes several tools and utensils that can help you draw using very precise lines. Therefore, you can use axis, grid lines, numbers, tips, outer frame and mouse coordinates to plot the mathematical functions. Alternative, you can choose the transparent background, if you are feeling creative.

In the addition to the background helpers, the program comes with various tools that can lend you a hand with setting the correct values and parameters. Simply put, the application incorporates a basic calculator, fx evaluator as well as a triangle, integral, derivative and composite solvers. Last, but not least important the utility comes with a 3D viewer where you can analyze the effects and details of your plot.

You should know that the program allows you to change the axis and background color as well as specify an exact plot range where you think your graph could fit. Once you are done with your project, you can save your image to PNG, BMP or JPG.

History

Simple Grapher V1.2 Screenshot

Simple Grapher was released in 2013, it was very simple (that is why named Simple Grapher) and had very simple features (plotting functions and simple inequalities), it also had a very bad GUI. But in few next versions it grow very fast and the program could support lot of features, and in November 2015 the program changed its name to Simple Grapher Plus, because it became very developed program and had a completely new interface.

Plus Version

In (2 November 2015) the program named Simple Grapher Plus, because of many changes was done in that version, Including:

• New way to plot functions (high quality pictures)
• completely new interface
• faster plotting
• many other improvements
