General Mathlets for use with Differential Equations by Noonburg and Decker
For graphing first-order differential equations and/or slope fields use First-order Grapher
For graphing systems and second-order equations (when written as systems) use Systems Grapher
In order to get a hard copy of a graph from one of the graphing applets above, proceed as follows:
Windows: Adjust the browser window to make it as small as possible while still being able to see the graph. Hold down Alt and while holding it down press PrtSc (if you are using a laptop you may also have to hold down Fn). Then go to a word processing document (probably Word) and paste (Ctrl-V). You can then print the document.
Macintosh: To capture a portion of the desktop, hold down Command(Apple) and Ctrl and Shift all together, then press 4. A cross-hair cursor will appear and you can click and drag to select the area you wish to capture. Go to word processing document and paste (Ctrl-V), then print the document.
