Graph is a powerful program for graphing mathematical functions on coordinate systems. It supports three types of functions: standard y=f(x), parametric x(t), y(t), and polar r=f(t). You can also plot two-coordinate x-y graphs, add shading, draw curves, and add text to functions.
Getting Started
Once you download the program, you'll find a simple interface that highlights the workspace. The first step to plotting graphs is adjusting the X-Y axes (or you can use the default settings). After that, you can start tracing graphs by inserting functions.
Using the Function Menu
From the top menu, you have access to all the tool's services. By selecting "Function" and "Insert Function...", you can insert predefined functions and then edit them. You can also create a custom function. In the same menu, you'll find "Insert series of points...", where you can enter X and Y values to plot the graph and customize the physical properties of the coordinate marker.
Other functions in the "Function" menu include adding fill, inserting tangent, inserting trend line, and inserting equation and inequality, among many other services.
In the "Calculate" menu, you can compute the length between two points on the curve, calculate the area between the function and the axis, evaluate the selected function for any value, and prepare an evaluation table for a defined interval.
Final Thoughts
Graph is a very good platform for graphing mathematical functions and evaluating them. What we highlight about the tool are its visual functions, such as inserting colors and fill. Graph is a free program available for Windows operating systems. It's true that it has a few years under its belt, but it works wonderfully. And you know what we say at NeoTeo: "If it works, don't question it"
