DUE THURS: Take-home quiz, as handed out today. The guidelines for take-home assignments (unless otherwise stated) are these:
No late quizzes will be accepted, so be sure you are present to hand it in. I aim to give it back on Friday so you have it to study.
Though you may use notes, the length of this quiz is about half the length of the exam, so aim for a half hour. If that isn't happening, you know what you need to prepare more over the weekend.

Here's a previous semester's derivative quiz. Do it as practice without using notes. Check against my answers tomorrow.
Friday Feb 24 Read Sec 16 and view short videos on these theorems (not included on test but need to start them to be on schedule, since we have an extra day before the test than two other sections).
Do p 136 #1, 2
Also, try this Implicit and critical number practice quiz.
Since we don't have the first derivative test (FDT) yet, you determine if x = c is an extreme is a local max or min from checking values very close to either side of each c. We'll be glad to have the FDT after the exam to do this!
Exam 2 preparation topics
Basic derivative forms (power, log and exponential)
Operations on derivatives (not discussed much but we have done automatically, like f'(cx) = cf'(x), (f + g)'(x) = f'(x) + g'(x), and so on.
Derivative of a product, quotient, and the use of the chain (composition) rule (all these entail the derivative forms in combinations)
Higher order derivatives, with Leibniz and other notation
Evaluating a function and its derivative at a given x
Finding equation of a tangent line using implicit differentiation
Marginal cost, revenue and profit phenomena again (non-linear functions this time)
Related rates (know very basic geometric formulas)
Critical points of a function (what they are and how to find them), local extrema (max and min)
On Monday you will have a handout with extra practice problems. I WILL NOT POST THIS. If you want it you have to come to class. If you have a valid absence, notify me.
Tues Feb 28 Keys to related rates and Exam 2 review
Note: I have added a problem at the end of the key, the multipart problems #13 on operations on derivatives.

Per your request, I will find some review questions from my own previous quizzes/tests. Watch this space. Or wait till Monday while you go over the HW to date.
The test covers Sec 17-24, 27-29.
Mon-Tues Apr 3-4 Over the next day I will post older materials, including several that were from my actual quizzes. With answers, since there is no time to do in class.
1. Here is an old quiz I gave on the D test, all worked out. Write the question and try it on your own, comparing your answers to the one on the quiz key.
2. We didn't review global (absolute) extremes on closed intervals. An easy topic but worth reviewing:
An important note: The SDT is not used to discover whether a critical point is a max or min, but to confirm that a value where f''(x) = 0 is a POI. But to check that I had concluded the max or min properly from the FDT, I plugged my crit pts into the second derivative and checked the sign. Negative means the critical point lies in an interval of concave down, hence I should have concluded that critical pt gave a local max. And vice versa.
