  Read 2.3 and 2.4 (at least through p. 110).
  Unless instructed otherwise, you may use a calculator in any way that is helpful to solve any "word problem" throughout the rest of the course. However, if you use it in some way other than simple numerical calculation, then you must show and/or explain what command (like Solve or Graph intersection) you used.
  2.3; 7, 16, 21, 25.
  Hint 7: Trophozorites are single-cell organisms, so when they "divide" it doubles the population.
  Hint 16: The "1 in n" chance is the number 1/n.
  2.4; 1, 55, 61, 91, A and B below:
  Prob A: Derive (show steps where it comes from) the trigonometric identity for 1 + cot²x by using only identities on page 105. First change to sin and cos, simplify to get one function.
  Prob B: In the triangle , find sin \(\theta\) in terms of x (with no trig function in answer).

Week 03: Sept. 6
- 3.1 Limit Reasoning File
- #7 Assignment
  
  Read 3.1; Formality of the page 134 rules will not be emphasized, but the conceptual introduction in previous pages is helpful, and you still need to understand all examples.
  3.1; 9, 10, 11, 12, 21, 22. (On 21 & 22 and throughout Calculus, you must use Radians.)
  On all that follow, use good notation to show steps or explain reasoning; just an answer will not suffice.
  3.1; 38, 41, 45, 61, 79, 95, 96(Do you need to know constants are positive?).
- #8 Assignment
  
  Read 3.2.
  3.1; 50, 54, 55 on all three, show algebra steps as in class and/or explain reasoning in a sentence; just an answer will not suffice.

  3.2; 8, 9, 11, 14, 16,
  Hint on 8 through 16: You should be able to tell where it is discontinuous by just thinking about the formula domain. However, you may graph the function to decide the limit as you approach a discontinuous point.
  3.2; 24, 38.
  True or False: The function modeling Circadian Testosterone, on p. 122; 114, is continuous everywhere. If false, where is it discontinuous?
- #9 Assignment
  
  Read 3.3. (Also, do the 3.4 problems listed at the bottom.) Remember units in applications.
  3.3; 6, 20, 25, 33, 34, 44. You are required to follow the instructions below:

  4.2; 7, 19, 22, 29, 30, 33. (Instructions specify use product or quotient rule, so you must!)
  Hint for 4.1 probs: Easier not to use quotient rule, instead pull constants out front and/or use negative exponents.
  Hint on 56d: Units of BMI are just that, units of BMI. Describe the derivative as how much something changes for every what?
  Optional star (hand in separately within a week): do the pair of problems *(4.1;65 and 4.2;37 ).

  Read 4.3.
  4.2; 43, 45. (I don't like the 45a answer in back; a simpler form with only one H is better and makes 45b easier.)
  4.3; 11, 12, 22, 27, 33, 34, 38, 44, 51, 52.
  On 51 "explain the discrepancy" by showing that one answer can be algebraically converted into the other.
- CrowWhelk File
- Review #1 Friday 9/24 in class plus take home due by Monday at start of class.
  Covering material on assignments #1 through #13 (including chain rule).
  
  Usually three or four pages with space to work on the test.
  Notation and showing your work is important, not just answers.
  Similar to the variety of problems from the homework.
  Graphing calculator (bring one) use is unrestricted BUT:
  
  Mark how calculator is used beyond simple number crunching; in particular, mark if you use calculator graph (sketch), solve or algebra (enter an algebraic expression to get simplification).
  
  Limits and Derivatives must show "hand" steps and reasoning.
  
  You must follow instructions, e.g. a particular problem may say:
  
  use definition of the derivative (so answer or derivative rule are worthless), or
  
  use quotient rule, or
  
  use logarithms to solve.
  If you have extended-time accommodations or other reason why you cannot take this test in-class, contact Neidinger this week by Thursday to arrange pick-up and return.
  
  While in-class part is closed book, the TAKE HOME part is OPEN BOOK: You are allowed to use of your text book and your notebook of materials of all kinds (including e-files) that you have gathered. Use of spreadsheet software will probably be necessary and you may use Desmos or other online calculator (tell me if you do). You MAY NOT get assistance from anyone else or use the internet to research how to do a problem. You may not reference other materials, not gathered in your personal collection before picking up the test.

  Read 6.4 Example 2 only (for now).
  Read 4.4.
  I suggest the following unusual order of sections and problems.
  4.3; 56, 58, 62ab.
  6.4; 15, 18, 19, 13. (13 is trickier than the other three.)
  4.4; 3, 8, 15, 21, 27.
- #15 Assignment
  
  Read 4.5.
  4.4; 41, 48, 60 as below, 67.
  4.5; 7, 14, 16, 23, 37, 57.
  Hints on 4.4; 48: You may use calculator graph (y1(x) for V(t)) or Desmos to answer a,c,e. On c, may find intersection with y=0.5. On e, get value from graph (V'(240) in Desmos) but try symbolic derivative for practice (evaluation optional).
  On 4.4; 60: Just find I' for r=4,n=3, but leave the rest of the constants as letters; you don't have to do parts a and b. This prepares you for the evaluations of parts a and b, but these are OPTIONAL and most easily done by typing the formula into some computing (TI-89 or Desmos) where you can specify constants (b=8) and evaluate at points.
- FALL BREAK: No office hours or help sessions on Thursday or Friday. Enjoy the time off!
Week 07: Oct. 4

  Read 4.6
  On 40 may get derivative from graph, on all other problems you must show finding the derivative formula.
  4.6; 3, 7, 10, 18, 21, 33, 35, 38, 40.
  p. 312; 76.
  On 76: Plot over 0 to 2 sec. Measurements are positive going counterclockwise and negative going clockwise (as is usual in math). So in d, positive acceleration corresponds to counterclockwise force.
- #17 Assignment
  
  Read 5.1 & 5.2.
  5.1; 17+, 26+, 29+, 32+, 41, 44, 53, 56.
  The + means to also find (d) where a relative maximum is at x or relative minimum is at x.
  Hint on 17-32: simplify y' by common denominator or factoring.
  Hint on 53 & 56: The quadratic formula (p. R-13) can help find where derivative = 0.

- #18 Assignment
  
  You must find maximums or minimums by using the derivative.
  5.2; 15, 42ab, 46, 50, 53 as specified below.
  Hint on 42b: Include both + and - when you take a 6th root or ^(1/6).
  On 46b, do find the time but actual maximum value is optional.
  On 53: On (b-i), I require you to use csc functions instead of sin as in back of book. On (j-m), change to sin and factor out sin functions. On m, consider at or near endpoints 0 and pi/2. Throughout, try to avoid looking at the back of book unless necessary; it's fine if you "get ahead" of what they are asking on each step.

- #20 Assignment
  
  When finding max and/or min for the remainder of the course, you should show solving derivative = 0, not "maximum" from graph. (In a very technically detailed or complicated function, may use Wolfram Alpha, TI-89, or equivalent, to solve an equation, or even d( ) to differentiate, if you LABEL that is what you did.) Of course, assignments and problems may occasionally instruct otherwise.
  Read 6.1.
  6.1; 1, 7, 28, 47, 50+use 2nd deriv test, assuming all constants are positive,
  On 47: Graph only M, not derivatives. Hint: You can use quadratic formula to find the solution.

- The 6.2 outline of steps for Solving an Applied Extrema Problem is pretty good -- I emphasized step 3 in class. I would combine steps 4 and 6 into the following advice:
  Alternative ways to decide if a critical number c is a max or min:
  First Derivative Test (sign of f' on sides)
  Second Derivative Test (f''(c) sign)
  With domain endpoints, compare f values (at all critical points and endpoints)
  By graph (showing approximate extrema location that match your exact c)
  Say "physical reasoning" when only one critical number and physically it must be max (or must be a min).
  Pick any one of these but remember to check one. (See the CAUTION after the book outline.)
- #21 Assignment
  
  Read 6.2
  6.2; 4(non-negative x and y is important; why?), 13, 20, 30, 32, 40, 42.
  Hint on 13: think of energy "cost" by using relative cost/mile where cost/mile on land is 1.
  *Optional Star: Do two more problems: 6.2; 44 and the following Problem A:
  Not only dogs know calculus but light does too! When light hits water it bends because it moves faster in air than in water. The angle is given by Snell's Law shown on p. 116. Derive this law by minimizing the total time for light to go from start to finish. From upper left point to lower right, label constants for the vertical distances through Medium 1 and Medium 2 and the total horizontal distance. The variable is the horizontal distance x in Medium 1. Take derivative of total time and set it equal to zero. Do not solve for x but, instead, interpret the ratios as trigonometric functions and rewrite as Snell's Law.

  Read 6.5 but replace p. 352 with the following: The linear approximation of f(x) for x near a is
  f(x) ≈ f(a) + f '(a)(x-a). This should approximate any f with a line, as in the point slope form f(x) ≈ y₁ + m (x-x₁).
  6.4; 30, 36.
  6.5; 1, 25, 29, 32, 35: do all these problems using differentials.
  Exercises: For each of the following, write down the linear approximation f(x) ≈ f(a) + f '(a)(x-a) for x near a; then, if requested, test it by using it to approximate the specific value(s). (An example answer looks like: x^5 ≈ 1+5(x-1) for x near 1; test (1.003)^5 ≈ 1+5(.003)=1.015 (actual 1.01509...).)
  A. f(x) = sin(x) for x near 0; test sin(.03); test sin(-.12)
  B. f(x) = x^(1/2) for x near 25.
  C. f(x) = ln(x) for x near 1; test ln(.996).
  D. f(x) = (1+x)^n for x near 0; test 1.001^37.
  The "Quiz" is a way to record your grade out of 10 from in-class corrections.

  If needed in-class, I'll give (at start of test or in problem):
  
  formulas for SPHERE and CONE on p. A-10 but know other formulas on that page.
  
  D(a^x) = (ln a)a^x and D(log_a x) = 1/[(ln a)x]. Memorize all other derivative rules that we have used.
  
  In-class is probably three pages with space to work on the test.
  Pick up TAKE HOME part due Friday.
  Notation and showing your work is important, not just answers.
  Similar to the variety of problems from the homework.
  Graphing calculator (bring one) use is unrestricted BUT:
  
  Limits and Derivatives must show "hand" steps and reasoning; Maximums or minimums must be found by derivative (unless specifically told that you may get it from graph).
  
  Mark how calculator is used beyond simple number crunching; in particular, mark if you use graphing or symbolic calculator to do something other than number calculation.
  
  Problem instructions may specify "hand" steps or a specific technique (eg. second derivative test).
  While in-class part is closed book, the TAKE HOME part is OPEN BOOK: You are allowed to use of your text book and your notebook of materials of all kinds (including e-files) that you have gathered. You may use Desmos or other online calculator (tell me if you do), though same bullet requirements as above.

  Read 11.6 especially Example 2.
  Instructions for the following problems are changed to Moodle instructions below. When using online slope field on this homework, you may simply answer the question (say from online graph or table) and/or hand-copy the solution curve if you clearly label the axes ranges.
  11.6; 3 Replace the "and 400 are infected 10 days later" with "and at the beginning of the epidemic (when y=100) the infection rate (y') is 14 people per day." For (a) write a differential equation with initial condition (not the solution as in the back). Then find equilibrium values and make a qualitative sketch of the solution curve for this initial condition. (b) Use online slope field to estimate the answer to b.
  11.6; 10, 11, 12, 13. The first sentence should be prefaced with the word "Initially," since the physical tank might hold at least twice as much over time. On each of these problems, replace all instructions with: (a) Write a differential equation with initial condition for y(t), the lbs of salt in the tank at minute t. (b) If the DE is autonomous (10 & 13), find equilibrium values and make a qualitative sketch of the solution curve for this initial condition. If not autonomous (11 & 12), use online slope field to make an accurate sketch over 100 minutes. (c) Does the trend make physical sense?
  11.6; 14, 16. As intended in the text; write and solve the separable DEs.

  Show u and du (with change of limits) whenever it is not exactly an antiderivative rule. Exception: a linear u=kx+c, may simply produce a 1/k in the antiderivative, without showing u.
  
  Bring a calculator, especially for numerical evaluation of integrals (by calculator approximation, "hand" trapezoidal rule and/or simpson's rule). Be able to use a online slope field output to draw in solution curve for a given initial condition. Calculator use unrestricted BUT:
  
  Limits and Derivatives and Antiderivates must show "hand" steps and reasoning.
  
  Mark how calculator is used beyond simple number crunching; in particular, mark if you use calculator to graph, solve, or algebra.
  
  Problem instructions may specify "hand" steps or a specific technique or formula.
  While in-class part is closed book, the TAKE HOME part is OPEN BOOK: You are allowed to use of your text book and your notebook of materials of all kinds (including e-files) that you have gathered. You may be asked to use class online Apps and may use Desmos or other online calculator (tell me if you do), though same bullet requirements as above. You MAY NOT get assistance from anyone else or use the internet to research how to do a problem. You may not reference other materials, not gathered in your personal collection before picking up the test.

To complete course feedback surveys, students should go to http://moodle.davidson.edu and login. Students will be able to login to Moodle and access the survey even if you have not used Moodle for your course. Once logged in, they should see an “EvaluationKit” box on either the right side of the page or at the very bottom of the page (it is at the very bottom of the page on a mobile device). Some users need to use an incognito browser window in Chrome or a private browser window in Firefox in order to see the box. Please note that this box appears on the Moodle homepage, and not the page for your individual course. From there, they should click on the link that says, “Click here to complete your course feedback surveys” and then select the appropriate course (if any student is enrolled in more than one of your courses, they should pay careful attention to the course title). They should click on your course to begin the survey. Once they submit the survey for a particular course, the link for that course will disappear. Students who are unable to attend your class during the normal time will be able to access the survey on their own until December 7.
Current Known Issue: Some users cannot see the EvaluationKit box on their Moodle homepages or the box appears without a link. This issue is typically resolved when using an Incognito or Private browser window in Chrome or Firefox.
Final Exam -- Self-scheduled exam system.

The final exam is comprehensive and will cover a selection of problems from throughout the course. Expect similar to the variety of problems from the homeworks and tests. Problems might include ideas from multiple sections. Be able to do the last homework; the last follow-up lecture is optional, though you should know the name "chaos" (for when an iteration bounces almost randomly around within a range of values).

Expect nine or ten pages with space to work on the test. If you use any scratch paper, you must enclose it in your exam envelope. This is designed for about 3 times a 50 minute test (2.5 hr), but you have up to 3.5 hours max in an exam session.

Bring a calculator, though derivatives and antiderivatives should be found by hand unless otherwise instructed. Otherwise calculator use is unrestricted but write how calculator is used for anything beyond simple number arithmetic. Some problems will specify things to show by hand, but I always want to see all steps you take using good notation.

Everyone will be required to take the exam in 3.5 hours during one of these periods. I suggest you plan on the full 3.5 hours and if you finish early, great. (Those with accommodations may extend the time as arranged; if the system is closed, return to slot in Registrar's Office door, writing time returned on the envelope card.)

Wednesday, Dec. 8th	8:40am – 12:15	1:40 – 5:15pm
