**Office Hours:** Tuesday 1:50-2:50, Friday 1:15-2:15, and by appointment. **Change: On Friday, April 6, **my office hour will be moved to 2:30-3:30 due to meeting conflict. (I'll also have 15 minutes 1:15-1:30 if you'd like to stop by for a quick question.)

About Homework:

We'll use webwork along with some written problem sets.

Our webwork course page is: https://webwork.math.uga.edu/webwork2/Math2700_Rider_S18

Some problems require slope field/direction field analysis. Here's a plotter that may be helpful:

Your username is your myUGA id and your password is your 810 number.

For example:

Harry Dawg's email address is hdawg@uga.edu. This means his WebWork username is hdawg.

Harry Dawg's student ID number is 8101234560. This means that his WebWork password is 810123456.

Unless specified, you have an unlimited number of tries for each problem. The assignments are not timed, but will need to be completed before the due date.

Each homework set can be converted into a .pdf file, and thus can then be printed. You do this by selecting the Homework Set, click "Download PDF or Tex Hardcopy for Current Set", then "Generate hardcopy.." at the bottom.

To use webwork off-campus, see VPN instructions
