I'll be posting a grade record with estimated current course grade in the next day or so.
We'll be talking about finding the centroid (aka center of mass) of planar regions on Friday. It can be mildly surprising to find that the centroid may not be inside the region itself. Here is a little discussion, with an animation, illustrating such a situation.
I didn't do the best job discussing the leaking bucket problem, so here is a better explanation. It is in terms of time, which is the classic way the "leaking bucket" problem is seen.
Here is a review sheet for the second midterm exam.
Here are some hints and solutions to the integral collection I handed out on Friday. Enjoy!
Writing problem #2 is now due Monday, Feb. 11, instead of Friday, Feb. 8.
Here are the scores from the first midterm so everyone can get a sense of how they did relative to everyone else: 39,49,59,60,61,61,62,64,64,64,65,65,66,66,66,67,67,68,68,68,68,68,68,69,69,69,71,72,72,73,73,74,74,74,74,75,75,75,75,75,75.
I'll post answers soon.
Here is a review sheet for the first midterm.
I've added a link at right to my archive of old exams.
I was looking over the homework assignment for next week, and decided that there is no reason to do 5.1 #22 (b), so just do 5.1 #22 (a).
The worksheets will be used on most Thursdays in this course, and links to them can be found on the Course Calendar at right. Please print the appropriate worksheet and bring it with you to quiz sections on Thursdays.
Here is an applet illustrating Riemann sums, something we'll be discussing in the first week of class.
