Today

I am sorry for the last-minute notice, but there will not be a lecture today. There will be a lab at the usual time.

HW2 #7

Q1: On problem 7 (Moving a Charge) of the second homework set I keep getting this error message when I input my answer in a variety of different ways: "There is an error in your submission. Make sure you have formatted it properly."

Q2: I'm sure I have problem 7 right, but it is being marked wrong.

I've gotten these questions many times already, and in almost every case you did have the right answer. For some reason this problem is weirdly particular about the order the operations (superscript, subscript, square root) are put in.

If you definitely have the right answer, and can prove it (screen shot, copy & paste, etc), show me and I'll just go in and override your score for that question to give you full credit.

If this happens more than (roughly) 20 times, I will decide it is not worth the effort anymore and will give everyone full credit on #7 :-)

eLearning FAIL

Right. By default, eLearning chooses not to show you any new grades until I explicitly tell it to release them for student view. Basically, this means that my upload earlier today did not show up for you.

I think it is fixed now, and you should be able to see all of your grades.
