  • Fri, Feb 12th - Heating and Cooling Intro, Instructions on submitting Maple files:
    Step 1: Go to 203 Walker
    Step 2: Click on the apple (top left) and release on Chooser.
    Step 3: Double-click on AppleShare (in the top left of the chooser).
    Step 4: On the right, under "Select a file server", scroll down and double click on "hypatia.math.appstate.edu".
    Step 4: Under name, type "3130", and under password, type "3130". Click on "Ok".
    Step 5: Double click on "Shared Folder", which will appear on the right hand side of the desktop.
    Step 6: MAKE SURE the name of your file is in the correct format: hw2sarahjeff.mws for homework assignments, p81nums5and15.mws for problems we worked on in the lab. If it isn't, click on the name part of the file and change it!
    Step 7: You will see a file labeled "3130" in the Shared Folder. You cannot open this file, but you can drag files over to "3130" and submit them via releasing them on top of "3130" - be sure to do step 6 before dropping files to ensure that your work will not be lost.
