Children often enter into the world of algebra, calculus and physics being presented with formulas that get more and more complex as classes progress. Usually there is a section on graphing equations involving simple parabolic graphs of equations that are easy enough to solve. However, many times these lessons are brief. The importance of understanding the graphical nature of formulas cannot be understated, because the graph represents the physical and "real" nature of mathematic and scientific equations.
The value of the Runiter Company's graphic tool for Windows, called the Graphing Calculator 3D, is that some of the most complex formulas and equations can be viewed and manipulated in an impressive 2D and 3D format. The viewing window reveals a 3 dimensional world where the graph has depth, and can be swiveled turned and manipulated by the cursor.
Graphing Calculator 3D
is available as a free downloadable graphing calculator for Windows. It plots 2D and 3D graphics, and the graphics are completely customizable with various colors, shades and shadowing. The free edition has limited features, but it is functional enough to be extremely useful in any classroom setting or to assist children with their homework.
3D Graphing Calculator Main Screen
This tool is easily one of the best free graphing calculators for Windows. If the impressive quality of the graphics wasn't enough, the number of graph features that you can customize combined with the fact that you can graph multiple formulas in one 3D chart makes this one of the more powerful and useful 3D calculators available online. The graphing pane is shown on the right, the formulas and customizations are on the left, and a removable data spreadsheet displays in the center.
The Calculator View
If you click on View->Keypad, the graphing calculator keys will appear at the bottom of the left pane. The functions available on this "virtual" calculator are pretty impressive, including trigonometric functions, standard keys like square root and log, as well as additional functions like random, integer, floor, ceiling and more. This keypad makes plugging formulas into the equation fields a lot easier than trying to what the correct formula symbols and operators are.
The 3D Graph View
In the right pane, you'll find the impressive graph view. You can select between 3D and 2D mode, and just to the left of the graph you see the optional table data with sample points plotted out. You'll find that the 3D plotting feature does an impressive job with shading and coloring in order to reveal the curves and shape of the graph as the points are plotted throughout 3 dimensional space.
Rotating the 3D Graph
One of the most impressive features of this software, and what makes the software so wonderfully interactive is the ability to grasp a section of the plotted shape with your mouse and then rotate it around a sort of invisible axis at the very center of the screen. Depending where you initially click, the graph will rotate in one particular direction. By manipulating the shape in this way, you can show your students all of the intricate shapes and unique features that different formulas generate. There are few things that inspire students more than seeing abstract ideas turn into real, tangible objects in the real world. That is why this tool can serve as an excellent source of inspiration for students to learn advanced mathematics.
Graphing in 2D Mode
While the 3D functionality is the most impressive feature of this graphic calculator software, you may sometimes need the simple ability to create a 2D graph as you would on a standard scientific calculator. Utilizing the two variables, x and y, you can type your formulas and immediately see them plotted out on the 2 dimensional plane.
A Function Library to Save Formulas
Either educators or students will come across standard formulas that they need to use often. By clicking View -> Function Library, you can access the storage area for your functions. The library has categories for engineering, finance, physics and more. This makes it a snap to store common formulas for later use. Many formulas have values that change while the structure remains the same - and this library allows the student to recall the formula, tweak those values and then replot all of the points to get a good representation of every possible point within 3D or 2D space. The quick graphical representation allows the student to quickly correlate how each variable in the formula affects the other.
The beauty of this software is the ease with which you can simply type in one equation after another, and watch as the graph is instantly plotted in your 2D or 3D view. The software works quickly, with virtually no lag. You can simply tab to the next field and type in another formula, and watch as each of them are charted together within the same virtual space.
Complex Charting Ability
This amazing free graphing calculator for Windows lets you overlay graphs. This can have important uses in many different disciplines, as a way to display and locate where certain elements of each equation may interact (wherever they intersect). Presenting equations in such a graphical way presents data in a format that the human mind can more easily grasp and analyze.
Whether you're a scientist looking to simplify data that you've collected, a financial expert looking for a way to graphically represent financial estimations, or a science teacher trying to explain physics to your students - Runiter's Graphing Calculator 3D tool can provide you with the tools that you need to help children or adults grasp otherwise complicated concepts and ideas. Download this 3D calculator today and give it a try, it may come in handy in more ways than you may think.
