DiffyQ

(Nostalgic? See the 2018t and 2018g, 2017t and 2015t, 2015g, 2014t pages [18 exams], as well as the 2013t, 2004g, 2003g, 1994 page [18 exams].)

Individual Optional (DiffyQ) project

...will be due slid u n d e r room 402 Little Hall my office door (Little Hall 402, Northeast corner) , by 2PM, Thur., 25Apr2019.

The IOP must be carefully typed, but diagrams may be hand-drawn.

At all times have a paper copy you can hand-in; I do NOT accept electronic versions. Print out a copy each day, so that you always have the latest version to hand-in; this, in case your printer or computer fails. (You are too old for My dog ate my homework.)

Please follow the guidelines on the Checklist (pdf, 3pages) to earn full credit.

. Our Teaching Page has useful information for students in all of my classes. It has my schedule, LOR guidelines, and Usually Useful Pamphlets. One of them is the Checklist The checklist (pdf) which gives pointers on what I consider to be good mathematical writing. Further information is at our class-archive URL (I email this private URL directly to students).

In all of my courses, attendance is absolutely required (excepting illness and religious holidays). In the unfortunate event that you miss a class, you are responsible to get all Notes / Announcements / TheWholeNineYards from a classmate, or several. All my classes have a substantial class-participation grade.

Material to learn

Look Ma! All 10+bonus+bonus DfyQ quizzes (pdf). [Friday, 03May2019]
The useful Euler-Mascheroni constant and Gamma (pdf). See also W: Gamma fnc and Euler's constant. A place where the Polor-coordinate Trick is used, is the normalizing constant of the Gaussian distribution.
For the curious: The Gamma fnc, and Volume of the n-ball (pdf).
The Laplace transform (pdf) has an example, a simplification of tapping on a bell. Also available is a small Table of Laplace transforms (pdf).
Citizens United in applauding the essay-liberated Class-U (pdf), with its nifty-diffty trusty-dusty compendium of short-answer questions.
Algorithms for solving some differential equations (pdf) [DiffyNotes]. [I use this for class lectures. Our textbook will be used for reading assigments and as a problem-reservoir.]
Folks found themselves Hooked by the suspenseful Class-T (pdf), people hanging on to the edge of their seats, ready to spring into action EXACTly when the situation was critical; nothing could damp their enthusiasm!
Headlines proclaimed Class-S (pdf) a A smash hit!, with its clean two-tone format, and nifty freebie (S1a) question.

For the polynomial-degree question, examples one and two.
Our Syllabus has exam dates; Same syllabus as a PDF.
Wikipedia: W: SoV W: ODE.
W: Complex number. W: (skim) Linear DE. W: Exponential function.
W:(skim) Differential Eqn.
Read eventually: W: FTODE, Picard-Lindelöf theorem.
The Math-Greek alphabet (pdf).

Textbook: Fundamentals of Differential Eqns with Boundary Value Problems, (7^th edition). Author: Nagle, Saff & Snider. [While that is the official textbook, you may use the 6th, 7th,8th, or 9th editions.]

We will also use Wikipedia and perhaps other online sources.
