(4/30) Office hours/Help next week will be at the following times:

M : 12-3

W: 10-12

If you can't make these times, let me know and we can try to arrange something.

(4/29)

I will be holding office hours tomorrow, the 30th, from 10AM -12 or so. Depending on how many people show up, we may move to a classroom. If so, I will post a note on my office door to let you know where we went in case you show up after 10.

(4/21)

A number of you have expressed interest, so I have decided to allow you take a third test if you would like to get your test average up a bit. If you want to do it, you will have to arrange a time to meet me and take it sometime next week(Tues or later). it will cover sections 7.1 &7.2, 5.1, and 5.2. This seems like a short amount of material, but topics will include functions of 2 variables and their domains, partial derivatives, competitive and complementary items, 2nd order partials, elementary indefinite integrals, and indefinite integrals requiring substitution. If you do not take it, your test average will just be the average of the first 2 tests.

Also, I will hand out a final take home quiz on Thursday to be turned in on the day of the final. It will be optional and if you turn it in it will count only if it helps your average. If it does, you will be graded on your best 6 out of 7 quizzes; if not, you will be graded on your best 5 out of 6. It will cover sections 5.3, 5.4, and 5.5.

Finally, I will hand out a practice exam on Tuesday that we will start to work through at the end of class and on Thursday. Everyone please make sure you attend class next Thursday because we need to do course evaluations.

[ for #67, you can draw the tangent lines in the following way: once you've graphed the function Y1=.06204x^2 -4.063x + 112.76 and set the window to the recommended dimensions, push {2nd} then {PRGM} to access the DRAW menu. Select option 5 (Tangent(), and then move your cursor to the desired point on the graph(or you can just type in 2.5) before hitting {ENTER} to draw the line. To erase it , go back to the DRAW menu and select option1, which is ClrDraw. You may want to do this for the Example we did in class of the change in profit at x = 2.5 for the function 50(-x^2 -10x+20). When you do, you will see that the resulting tangent line at x = 2.5 has the same slope as we found by calculating P'(2.5)]
