S28-O3 WebWork: This is a FREE FOR YOU online homework system. I will be giving some supplementary assignments using it, including some extra credit and "techniques of integration" practice. It isn't hard to use, and will even let you check correctness of your answers before submitting them.

I would like everyone to try the first assignment, which is called "Demo", before 4:00PM next Tuesday Oct 3 (but preferably before class so you can ask questions in class if you have problems). These are some simple problems you should all be able to do, but will give you practice working the interface.

Some Review Information

Exam 2 solution. (Video, no sound.)

(Might not work on all browsers.)

Extra Credit Homework: the Weierstrass "half-angle" substitution

(Due November 28 - after TG break -but it might be easier for you to do it now, especially as there will probably be other videos to watch over the break.)

First, watch THIS VIDEO on the half-angle substitution. (It is only 5 minutes!)

Next, do THIS PROBLEM SET using the substitution.

You are encouraged to both watch the video and do the problems with classmates, but please do not just copy their answers!

Nov 14 Power Series (9.7)

Quiz on 9.6, 9.7

9.9/3,6,7,9, 13, 19, 21, 22, 25, 31, 37 (19-25 are practice in error estimates; 31 is an example of one of my favorite applications of series); look at 45

(If time: start numerical integration, 8.6: Trapezoid rule and Simpson's rule)

Lecture notes for Taylor remainders

Video (optional):

Derivation of the Taylor error estimates.

(While this is optional, anyone thinking of majoring in math or physics or EE should definitely watch it, and for anyone else, it is a nice application of IBP.)

Another Extra Credit Assignment: Hyperbolic Trig Functions

1. Watch THIS VIDEO on the hyperbolic fiunctions, Section 7.7

(Here it is in a different format, if the other one didn't work.)

2. Next, do the WEBWORK assignment called HyperbolicFunctions.

You are encouraged to both watch the video and do the problems with classmates, but note that WebWork randomizes problems, so you can't just copy your friend's answers!

Due: Last day of class (Dec. 7)Day after the final exam: 10AM, Dec 14

The remainder of the semester will mainly be on Ordinary Differential Differential Equations (ODEs), which appear in Chapter 16/17 of the text. If your copy of the text does not have Chapter 16, don't worry; Chapter 16/17 of the text is available online here (click) as a pdf.

So that I can focus class time on examples, I am uploading some videos that supplant my lectures. YOU SHOULD WATCH THESE VIDEOS BEFORE WE GET TO THE DISCUSSION IN CLASS. (In fact, you might just want to watch all the videos over TG break.)

Viewing these videos is not optional, and I might quiz you on them at the beginning of the corresponding class.

Nov 28 Finish numerical integration (8.6)

Exponential Growth (8.5) and Separation of variables

Start: General ODEs (16.1)

You should read 7.5, also at least skim 16.1 (up to around Page 5)

Videos:

1. Introduction to ODEs

(Here's a more cellphone-friendly version)

This video introduces the terms: Ordinary differential equation, Initial value problem, Initial condition, order of a differential equation, particular solution, general solution

2. Separation of Variables

Don't forget to go to full screen video when viewing these.

You should watch these before class on Nov 28!

Nov 30 Finish: General ODEs. Do: 1st order linear ODEs

GRADE PREDICTOR.
This gives my best guess(es) as to what your grade would be if you get a solid A or a solid B on the final exam.

(NOTE: They do NOT include the last quiz, the WebWork work, or any extra credit, and do not exclude quizzes excused for illness etc. Also, while the predictor reports +/- grades, the actual class grades will not be +/-)
