The following lists weekly assignments, broken down into one or two days. You'll see Friday HW is often a little longer than other days.

There is significant use of 'flipped learning', wherein you view a video before I teach the material. These are SHORT and HELPFUL. They are never much different from my approach to a topic.

The boldface **day** indicates the assignment given date. You are expected to have done this HW by the next class meeting. Your preparation is essential to your progress. I will sometimes check HW at desks, so it's a great idea to keep it in a separate notebook or folder.

WEEK 1

**Wed**: Read Ch 1 in Course Notes for Math 220 (Geoghegan and Brewster)

Do p 5 exercises: #1, 2, 7, 8

View first five videos at SUPPLEMENTAL MATERIALS

Find further review at: Simplifying radicals with constants only, With variables and Many videos on negative exponents

**Fri (weekend)** Read Ch 2 in Course Notes for Math 220 (Geoghegan and Brewster)
on
View: Finding domain of a function

Do p 16 exercises: #9-15

View Graphing piecewise functions

Do rest of Ch 2 exercises, pp 15-16, #1-6

Although I have not done chapter 3 in lecture, please do read it over the weekend and watch the videos.

Read Ch 3; view Break even problem 1 and Break even problem 2

WEEK 2

**Monday** The first problems in Ch 3 cover the review of lines, whose *general* form is px + qy + r = 0.

Do Ch 3 p 26 exercises #1-5

At the VIDEOS link, view the first group of videos (Cost, Revenue, Profit)

**Wed** Do rest of Ch 3 exercises pp 27-28 #6-16

Read Ch 4 (Exponential and Logarithmic Functions) View Graphing exponential fcns (up to minute 7:30) and Graphing log fcns

Do pp 43-44 #1-5

Topics for Quiz 1, Friday, covering Ch 2-3: Sketches of essential functions; finding domain of a function, using interval notation, composition of functions, equations of a line, linear cost, revenue, profit functions

**Fri** Here are some straightforward solving log and exp equation videos, by three different teachers, all fine!

Video 1, Video 2, and finally Video 3

Do exercises pp 43-44, #8 b e f g, 10 a c e f, 11 e f h, 12, 18, 19, 20 a-e, 21 b d f

WEEK 3

**Mon** No classes, Labor Day!

Per webpage – stay caught up on reading. Always read ahead and watch these videos.

Solving exp eqns, Solving log eqns Ex 1 and Ex 2

There are plenty of videos for solving equations, but people tend to have the most trouble with radicals. Watch these:

Solving an equation with one radical, Solving an equation with two radicals Solving rational inequalities

**Tues** DO THIS Solving equations and inequalities worksheet

Read Ch 5; view Compound Interest videos in VIDEOS

**Wed** Do Ch 5 exercises first set #1-7, and second set #1-4, 6, 7, 9, 10, 12

Hand in worksheet Fri for grade.

**Fri** Do the Effective Interest Rates exercises if you skipped in Ch 5

Read Ch 6 Limits and view Finding limits from a graph

Evaluate limits using properties, Ex 1

Evaluate limits using properties, Ex 2

More techniques for evaluating limits, Ex 3 (gives a little jump on continuity)

YOU CAN DEFINITELY DO first exercise in Ch 6 p 67 #1-12

If you need more help understanding Limits, see “Section 6” (that is, Chapter 6) block of videos in SUPPLEMENTAL MATERIALS

I often choose problems from the Supplemental Materials Worksheets for quizzes and exams.

WEEK 4

**Mon** Finish Ch 6 p 67 Exercises (through #30). My complete solutions are posted here and on solutions page Ch 6 solutions IGNORE #22

Also, do Supplemental Limits Worksheet and see the complete Limit worksheet solutions

Read Ch 7 and view first two videos under **Derivatives** at VIDEOS

**Wed** Watch the rest of the videos under **Derivatives** at VIDEOS

Also, check out these:

Just slope at x = a using limit of DQ

and

Slope at x = x1 (same as x = a) AND equation of the tangent:

Do Ch 7 Exercises p 71 #1 c, d, e, #2 c and Ch 8 Exercises p 77 #1-4

Brief quiz on Friday on Ch 6, 7/8. A few limits as well as eqn of line tangent to curve using limit def of derivative for slope.

**Friday** Read Ch 10 a couple times. Watch the videos again on derivatives.

Here's Patrick doing Power rule shortcut examples. You can follow his link to other examples if you need to.

Do Exercises in Ch 10 #1-5 and #6 a-d

WEEK 5

**Mon**

1. Finish Ch 10: As assigned Friday, you'll have no trouble *finishing* Worksheet worksheet on C', R' and P'

View Product rule examples and Quotient rule examples

2. Do Ch 10 #8-13 and #16 d-n

3. Ch 11, watch Chain rule explained by Patrick mjt

Read Ch 11 and view these *short* example videos:

Ex of chain rule for radical function

Ex of chain rule for natural log function

Many great examples of chain rule involving ln[u(x)]

**Wed** Do Ch 11 p 96 #1, and in each of the multi-part #2, 3, 4, do every other one. Also #6, 7 and 13 (every other)

*Read* Ch 12 (we've done the Leibniz notation – since this chapter should go before chain rule, I taught most of it already. A second derivative entails taking the derivative of a derivative. Don't worry about higher than derivatives than second.

Quiz on Friday on derivative computation (no word problems). I will put the 'forms' I talked about today on the overhead as a guide.

Here are Worksheet solutions for C', R' and P'

**Thurs** Prof Dave explains implicit differentiation

**Friday**

1. Re-read Ch 13 Implicit differentiation (ID); read Ch 14 Related rates (RR)

2. View videos, twice if necessary:

RR 1: Area of circle and changing radius rate

RR 2: Ladder sliding down the wall problem

RR 3: Cost and profit with respect to time

RR 4|Revenue problem 3. Do this worksheet, best you can, and see the same plus full solutions under it:

Related Rates Worksheet Solutions to Related Rates Worksheet

**Mon** Do Ch 14, #1, 2, 4, 9, 12, 13
