On the Math 223/224 Director's page you will find the syllabus with grade policy and distribution of points to tests and quizzes/take-home assignments and WebAssign. Also, several previous semester final exams (midway through, when 223 ends).

For WebAssign, our class key is binghamton 1995 8714

The e-book for Stewart's Precalculus 7e is in several places. It is easiest to go to My Assignments, where you will find the e-book, broken down into Chapters and Sections.

Find Steps to get to Kazmierczak videos here.

Exercises in Precalculus, Stewart, 7th ed. are to do addition to the WebAssign. They won't be collected, but you should have questions to ask in class.

WEEK 1 AUG 24-27

Summary of assignments for first week–if any exercises give you trouble, rest assured we'll cover them in class. Early exercises give me a broad idea of how familiar you are with fundamentals.

m( I didn't mean to include the App D for tonight! We aren't there yet. I took it off ~


See WEEK 5 for weekend homework.


Saturday Sept 18 and Sunday Sept 19 Weekend trigonometry videos


Here are 30 minutes of videos taking us from understanding where the points on the unit circle come from to graphing the sine and cosine functions from these points.

We named the x and y coordinates by looking at the special angles 0, pi/6, pi/4, pi/3 and pi/2. Here, Professor Norm Prokup does it with a bit of simple geometry (Pythagorean theorem), which will prepare you well for calculus – which after all relies on analytic geometry! Learn and enjoy ~

Trig 1, Trig 2, Trig 3, and Trig 4

Trig 5, Trig 6, Trig 7, and Trig 8

Don't forget to complete TAKE HOME #1

Catch up on WebAssign and textbook exercises. I will add a trig batch on Monday.

Check it out

Mon Sept 20-Tues Sept 21 Don't forget the midterm is a week from today, Monday. Here are a couple of items I promised today. They should help.

  • App D in WebAssign is due Sept 21 at night, the Midterm Review is due Sept 26, but I see it's not graded. DO IT ANYWAY to get ready for the Midterm. We can look at it in class assuming I have a working tablet by then
  • Readings in textbook: Sections 2.8, 5.5 and 6.4 (Inverse trig functions go on the next exam, but reading about them can help you see the solutions to the trig equations)

Wed Sept 22-Sunday Sept 23

  • Continue working on the Nutley High School worksheets and have questions ready for me

Weekend study for Monday's Midterm

  • Do the WebAssign Midterm Review if you have not yet completed it
  • Extra practice
  1. Transforming functions Sec 2.6: #7-51 odd (you did many of these in a previous assignment)
  2. Dividing Polynomials Sec 3.3: #5, 13, 17, 23, 27, 39, 57, 63
  3. Real Zeros of Polynomials: Sec 3.4, 31, 5, 9, 11, 17, 31, 55, 61
  4. Unit Circle: Sec 5.1: In #3, 5, 7 ask we show that certain points are on the unit circle. They are not the special angles of your unit circle. Yet all you have to do is show x^2 + y^2 = 1 and you did it. This is the Pythagorean identity. Also, #9, 11, 13, 23-37 odd


Wed Sept 29-Thurs Sept 30

You can start using the Stewart Calculus e-book on your Cengage site now. It's in the same box as the Precalculus book. I could have been using the calculus book's section numbers from the start, but I honestly did not understand the schema. The only one that wasn't replicated in the precalculus was the App D. Which I taught with videos and my notes. So…

  • Read App D in Stewart Calculus and if you would like to take another crack at the WebAssign for App D, I rescheduled it to Friday morning.
  • Read Stewart Calculus Secs. 6.1 and 6.6 on inverse functions and inverse trig functions and videos therein
  • Read Stewart Calculus Sec 6.2 exponential functions and videos therein
  • 8-O Looking ahead, but not by much: The next WebAssigns start coming due Monday Oct 8. Begin them now, after doing the corresponding reading and video. You likely know a lot of the concepts already. If you have a question, send it to me within the WA communication! Here's a summary of the WA schedule:

Oct 4 before class: CLASS WARMUP: Sec 6.2

Oct 4 end of day: Secs 6.1 & 6.6

Oct 6 before class: CLASS WARMUP: Sec 6.3

Oct 8 before class: CLASS WARMUP: Sec 1.5

Oct 8 before class: CLASS WARMUP Sec 1.6

Oct 8 end of day: Secs 6.2 and 6.3

8-) Friday Panopto recording

Friday Oct 1-Sun Oct 3

See the WebAssign that are due early in week and get those going, don't wait till you are late

Read Stewart Calculus Secs 6.2 and 6.3

View all Kazmierczak videos in text Secs 4.1-4.6


Mon Oct 4-Tues Oct 5

Do WebAssign CLASS WARMUP: Sec 6.3 before class on Wednesday

View the super short Where e comes from

Read Calculus e-book Sec 1.5 Limit of a Function (intuitive) and view the Kazmierczak and Mosely videos in Precalculus e-book Sec 13.1

Read Calculus e-book Sec 1.6 Calculating Limits Kazmierczak and Mosely videos in precalc text Sec 13.2

You can do WebAssign before they are due for most of the ones listed in last week's summary

Wed Oct 6-Thurs Oct 7

Here are the limit videos the Math 220s watch; you will find them helpful:

Finding limits from a graph (little rough quality, but good)

Evaluate limits using properties, Ex 1

Evaluate limits using properties, Ex 2

More techniques for evaluating limits, Ex 3

8-) Optional, good insight, might actually help you better understand the actual limits we have done:

Precise definition of limit

8-o Practice for mini-quiz and rest of course ;-)

I will add more problems to this for the skills test, which will be next Wednesday!

Fri Oct 8-Sun Oct 10

More of the Math 220 videos:

More techniques for evaluating limits, Ex 3

Ex 4 involving radicals

Ex 5 also with radicals

8-O IMPORTANT Infinite limits in which a function goes to positive infinity or negative infinity as x approaches a:

Ex 6 involving rational expressions


Mon Oct 11-Wed Oct 12

Change in plans – There is no skills test, due to a lack of time to thoroughly cover the rest of limits and review for Monday's final. I didn't figure Fall Break into my calendar.

8-O Do the following Stewart Calculus Exercises and have questions for any and all sections ready to ask in class 8-O

Sec 1.6, Exercises #1, 10, 15, 17, 19, 23, 25, 29, 31, 33, 45, 51, 54*

Sec 1.8 Exercises #3, 7-27 odd, 39-48 all

Did you watch Kazmierczak and Mosely videos for Sec 13.1 and 13.2 in Stewart Precalculus?

Here are the mini-videos I post for Math 220 on continuity:

Graph a piecewise fcn 1

Graph a piecewise fcn 2

Continuity and limits made easy

Discontinuities in a function (piecewise)

More inspecting for discontinuities of a piecewise function

Thurs Oct 14-Sun Oct 17 8-) Study well for the Math 223 final

Soon I will post a brief review video. Topics to study (see problems in Stewart and WA) are those since the midterm:

  • Unit circle values as always must be known to do anything involving trig fcns
  • Inverse functions: determining the inverse of a given one-to-one fcn; evaluating inverse trigonometric fcns
  • Logs and exponentials: evaluating or simplifying via log definition and log and exponential properties; finding domains, solving equations, graphing transformations in detail (intercepts, asymptotes, accurate shapes)
  • Limits and continuity: evaluating limits of all kinds; understanding continuity and finding points of discontinuity

I notice that WA does not have Sec 1.8 practice. So definitely do the problems I assigned.

Here are the two previous exams and solutions, posted by Dr Kazmierczak on the main website.

Fall 2015 final exam and Fall 2015 final exam solns

Fall 2016 final exam and Fall 2016 final exam solutions


8-) Review sessions: Part 1, Part 2, and Part 3
