Week 4 of m171
(§ 3&5, Mr. Lane)
13–17 February 2017

Math Learning Center (in Math 011) has tutors:
10am–4pm Monday–Thursday
and 10am–noon Friday

- weekend (11–12 February 2017):
start your review for Test 1
- Sample Test 1 was distributed Friday and posted on the class website (lennes.math.umt.edu/171/pdf).
- Solutions to Sample Test 1 will be posted Wednesday on the class website.
- The
*Test-1-review*assignment in WeBWorK opened Friday (10 Feb) and closes Thursday (16 Feb). Solving 3 or 4 problems per day would be a reasonable pace.

- Monday [d13] (13 February 2017)
WeBWorK:
RQ-2-5 closes at noon;
day-11 closes at 11 pm
- Study section 2.5 (
*The Second Derivative*). [**Note**: This topic was postponed from last Friday.] - Work on these items at end of §2.5:
1–4,
**5**, 7;**15**, 20, 21,**25**, 28; 33, 34, 37, 39, 41 - pre-class Learning Objectives:
- If g(t) is position of an object at time t, then interpret g′′(t) in terms of the object's motion. Hint: after interpreting g′(t), consider how to interpret changes in the values of g′(t).
- Interpret second derivative in terms of concavity for graph.

- Learning Objectives for class or further study:
- In the neighborhood of an inflection point, how is/are the tangent line(s) related to the function's graph?
- Suppose p and g are functions such that p′(x) = 1 and g′′(x) = 1 [for all x]. In what way(s) could graphs of p and g have different shapes?

- Study section 2.5 (
- Tuesday [d14]
WeBWorK:
RQ-2-6 closes at noon,
day-12 closes at 11 pm
- Study section 2.6 (
*Differentiability*).- Differentiable implies continuous.
- Continuous does not imply differentiable.
- Discontinuous at
*x = a*implies not differentiable at*x = a*.

- Work on these items at end of §2.6:
1–3;
5,
**9**, 11, 16; 17, 18, 23–26, 27 - Also work on these problems in section 2.5:
**26**, 29, 31 - Anticipate a quiz (probably based on some
*Strengthen Your Understanding*items in §2.3–2.5).

- Study section 2.6 (
- Wednesday —
Review for Test 1
WeBWorK:
day-13 closes at 11 pm
- Our text has several aids for study and review
at the end of each chapter.

- Thursday WeBWorK: Test-1-review closes at 8:00 pm
- Friday (17 February 2017) —
**Test 1**on sections 1.7–1.8 and Chapter 2.- Format will be similar to the Sample Test, but problems on that sample
are
**not**templates for this semester's Test 1. - You may use a non-symbolic graphing calculator
**only**during the last 15 minutes of this test. - Phones, MP3 players, tablets, and computers must be turned-off and out-of-sight.

- Format will be similar to the Sample Test, but problems on that sample
