In Mathematica, make a homework notebook by opening the appropriate section of the book and then deleting the problems that are not assigned. This is a better procedure than copying the assigned problems to a new notebook, because each notebook has some information about style that you want to have. Save your notebook by pulling down the "File" menu and selecting "Save As...". A window will pop up, and you will be able to specify the name of the file and where it should be saved. Put it on the "Desktop". Do not save directly from Mathematica to the floppy drive, as a bug that may corrupt your notebook has been reportedly associated with doing that!

If your notebook turns out to be too large for the floppy, you can save it in a special way without the rendered images. That will save a lot of space, especially if there are many three-dimensional graphical images in your notebook. Here's how to do it. Pull down the file menu and select "Save As Special". A window pops up with some checkboxes in it. Uncheck the box labeled "Include formatted text", and then click on the "OK" button. A window will pop up which will let you specify where to save the file. Don't put it directly onto your floppy!

Work the problems, saving frequently to the hard disk or desktop of the computer. Every 15 minutes or so, save your notebook, then enter the finder (application selector icon in the upper right hand corner), and drag your notebook onto your floppy drive -- it should get copied to the floppy. Each time you do this, use the next of your three floppies, so you have multiple copies of your homework saved. When you leave the lab, put the copy of your homework that was on the desktop into the trash. The next time you come into the lab, put the floppy in, double click on the floppy icon to open it, and use the finder to drag your notebook onto the hard disk icon in the upper right hand corner of the desktop. It should get copied rather than moved -- you can tell because a copy will remain in the floppy, and a copy status window will appear during the copy operation. Work with the version on the hard disk, just as before.

Leave some copies of your homework floppy at home, so that if you lose your backpack, you will not lose all your work.

Some students prefer to use "FirstClass" as a way of saving their homework. You do this by sending yourself a message with the homework file attached.

If you learn how to use "Fetch" in the "Network Services" folder, you can also deposit your homework files on your unix account on the students machine.
