Tips for Using SAGE
- If you're using OS X and get errors about "fork: Resource temporarily unavailable.", then create (or edit) /etc/launchd.conf and include the following:
limit maxproc 512 2048
then reboot. See [http://www.macosxhints.com/article.php?story=20050709233920660 this page] for more details.
[http://www.geogebra.org/cms/ GeoGebra] is a free and multi-platform dynamic mathematics software for schools that joins geometry, algebra and calculus. Here's how you can embed it in the SAGE notebook.
In GeoGebra: Create some geometric construction or plot an algebraic expression. See [http://www.geogebra.org/cms/index.php?option=com_content&task=blogcategory&id=69&Itemid=56 this page] for more details.
In GeoGebra: File> Export> Dynamic worksheet.
Open the .html just exported with a text editor and copy the <applet> section.
In SAGE notebook: Data> Upload the .jar and .ggb files just exported.
In SAGE notebook: Edit> Paste the <applet> section.
In the <applet> section, change codebase="./data/", you can also set some of the flags to true.
- Save changes, and you're done.
