This online calculator is able to graph in two or three dimensions. The advantage is the ability for all students to have the fastest, most capable calculator in class. Calc5 can be used to graph sin graphs, logarithms, and likely any graph needed in High School Math classes. A graph can include multiple functions. In order to see them, simply drag the graph. It is easy to zoom in and out of the graph. Students can take a screenshot of the graph in order to show in assignments or an online space. In Mac, simply hold the apple, shift, and number 4 key at the same time. Use the cursor (now a cross-hair) to drag a box around the picture and let go. The picture will be saved to the desktop. For PC, use the "Print Screen" button, then PASTE into any document or PowerPoint.
In the Classroom
Use this site to allow all students access to a powerful calculator. Students can graph class problems and notice the differences in the graphs and account for them. Students can predict the shape of 2D and 3D graphs from the equation being used. Share the site on an interactive whiteboard and use the board’s tools to draw atop or annotate the graphs.
At Home
Graphing calculators are expensive and always changing with time. Use Calc5 and have access to a powerful computer quickly and easily.
