WeBWorK: Covers the rest of Section 12.4, all of Section 12.5, and part of Section 12.6. Do any (partial) differentiation without technology.Handwritten:
12.4: 35, 38, 39
12.5: 19, 25, 26
12.6: 24
It is still important, in sections 12.4, 12.5, and 12.6,
that you do not use technology to (partially)
differentiate. Show work.
WeBWorK: Covers the rest of Section 12.6 and some of Section 12.7.
Ordinarily, on these sections I assign alot of problems. Because of the exam, I tried to keep the number of problems down ... partly by moving some of the problems I would ordinarily assign to the study guide. So you may notice, between the WeBWorK and the traditional study guides, quite a few problems from these sections.Handwritten:
None: I want you to know before the exam whether the ideas are all making sense
WeBWorK: Covers the rest of Section 12.7.Handwritten:
12.7: 24, 36
Feel free to use technology where appropriate in
these problems -- for instance, to differentiate,
or to solve for where a partial derivative is 0.
Do not use technology that simply does the
optimization or regression for you. Any technology
that you use, copy or print out and include with your
work.
WeBWorK: Covers Sections 13.1, 13.2, and 13.4.Handwritten:
13.1: 28
Part of the point in sections 13.1, as well as in the two sections below, is that you be able integrate. (You need to be able to recognize whether you should change the order of integration or not, for one thing ... and that requires recognizing whether a function is antidifferentiable.)13.2: 18, 26Therefore for all the written problems assigned this week, please antidifferentiate by hand.
In Problem 18, be careful. While double integrals can be negative, the volume between two surfaces can not be: when you subtract the volume under the lower surface from the volume under the top surface, the result will always be positive.13.4: 2
WeBWorK: Covers Sections 14.1 and 14.2Handwritten:
14.1: 30, 32
14.2: 18, 20, 56, 58
For problems 56 and 58, work through the problems all the way to the point where you would be ready to integrate, but don't actually do the integration. That is, parametrize the curve, write both f and ds in terms of the parametrization, and substitute everything into the integral (including limits of integration).
