Class 28 Recap (Wed Dec 11)

Schedule

  • WebWork: “Derivatives – Logarithmic” and “Derivatives – Implicit” extended to Fri Dec 13
  • Exam #3:
    • the take-home exercises for 50% of this exam were handed out in class, to be handed in on Monday Dec 16
      • see this post for an outline of the topics covered in the take-home exercises
    • there will also be a short in-class exam on Monday Dec 16, for the remaining 50%; these exercises will be similar to the take-home exercises
  • Final Exam Reviewhand in written solutions to the following exercises (either on Monday with Exam #3, or on Wednesday before the Final Exam):
    • #5 (logarithmic differentiation)
    • #7 (implicit differentiation)
    • #8 (tangent lines, linear approximations and differentials)
    • #16 & #17 (optimization)
    • #18 (using critical pts, intervals of increasing/decreasing, and intervals of concavity for sketching a graph)
      • we set up most of these in class, and/or did similar examples
      • the Final Exam Review exercises (including limited solutions) is available as a pdf on OpenLab Files
  • Final exam: Wednesday Dec 18

.We completed the applied optimization example we had started on Monday (FER #17), and then did a related rates example (FER #12).

Exam #3 – take-home exercises

Here is a summary of the topics and some relevant examples to study for each of the take-home exam exercises:

#1 (implicit differentiation): Final Exam Review (FER) #7; see also the example we did in Class 24 and Class 25, the WebWork exercises, and Sec 3.8.

#2 (related rates): Final Exam Review (FER) #12, which we discussed in Class 28; see also Example 4.1 and the “Problem-Solving Strategy: Solving a Related-Rates Problem” from Sec 4.1 of the textbook.

#3 (linear approximation): See FER #8(a), which we did in Class 27, as well as the examples (and graphs) at the start of Sec 4.2. You can also review the exercises from Exams #1 and #2 where I asked you to write equations of tangent lines (and sketch them).

#4 (applied optimization): FER #10 & #17; we covered the latter in Class 27 and Class 28 . See also the “Problem-Solving Strategy: Solving Optimization Problems” at the beginning of Sec 4.7.

#5 (shape of the graph and maxima/minima using the 1st and 2nd derivatives): See the solutions for FER #18, and the example we did in Class 26 and Class 27.

For the last exercise (and for #1 and #3, since they also involve graphs) you should use Desmos or a graphing calculator to check your solutions and help you sketch an accurate graph.

Class 27 Recap (Mon Dec 9)

Schedule

  • WebWork: “Derivatives – Logarithmic” and “Derivatives – Implicit” extended to Fri Dec 13
  • Exam #2 corrections (optional) are due tomorrow (Wed Dec 11)
  • Final Exam Review– hand in written solutions to the following exercises (on Wed Dec 11 if you have them finished, but if you need more time I will take them next week as well):
    • #5 (logarithmic differentiation)
    • #7 (implicit differentiation)
    • #8 (tangent lines, linear approximations and differentials)
    • #16 & #17 (optimization)
    • #18 (using critical pts, intervals of increasing/decreasing, and intervals of concavity for sketching a graph)
      • note that we set up #8 and #17 in class (see below), and we set up #5 and #7 last week
      • for #18, follow the example we did in class last Wednesday, and recapped in this class (see below)
      • the Final Exam Review exercises (including limited solutions) is available as a pdf on OpenLab Files
  • Exam #3:
    • this will cover the topics from the Final Exam Review listed above (plus related rates, which we will cover tomorrow)
    • take-home exercises for 50% of this exam will be handed out in class on Wed Dec 11, to be handed in on Monday Dec 16
    • there will also be a short in-class exam on Monday Dec 16, for the remaining 50%; these exercises will be similar to the take-home exercises
    • we will use half the class period on Mon Dec 16 to do some additional review for the final
  • Final exam: Wednesday Dec 18

We recapped the examples previous class on graph-sketching using the first and second derivatives, looking at a cubic polynomial f(x). We discussed these figures from Sec 4.5 which illustrate these concepts:

We then covered linear approximation (Sec 4.2), using FER #8 an example, and applied optimization (Sec 4.7), using FER #17 as an example:
