HW 4a and 4b are now available – here are highlights

HWs have been due on Fridays, but 4a and b are extended to the following Mondays. That way you have a few more days to work on them. Question: Is this a good idea? I need to know for future HWs.

Question #3 (see HW 4b) now has specific length requirements, which it did not on earlier HWs. Check it out.
