DiffyQ

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

. 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).

Optional: Individual DiffyQ project

...was due, slid u n d e r room 402 Little Hall my office door (Little Hall 402, Northeast corner) , by 2PM, Thursday, 26Apr2018.

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.

Textbook: Fundamentals of Differential Eqns with Boundary Value Problems, (9^th edition). Author: Nagle, Saff & Snider.

We will also use Wikipedia and perhaps other online sources.

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

The gentle Class-U surfaced Expialadociously! (on Wedn., 04Apr2018), but did not ask students to compute Exp(i·aladocious); which, anyway, equals Exp(−aladocous).
The Laplace transform (pdf) has an example, a simplification of tapping on a bell. Also available is a small Table of Laplace transforms (pdf). Related is Euler-Mascheroni constant and Gamma. For the curious: The Gamma fnc, and Volume of the n-ball (pdf).
Look Ma! All 18 DfyQ quizzes so far (pdf). [Wednesday, 18Apr2018]
With its Salty language, Class-T (now with solns) appeared (on Wed., 28Feb2018) out of the Briney Depths, to entertain the cognoscenti [Exactly what they were hoping for] as students effortlessly sprang through Harmonic motion with undamped enthusiasm.
Algorithms for solving some differential equations (pdf). [Thursday, 15Feb2018]
The exhilarating Class-S appeared (on Wed., 07Feb2018), attracting praise for its challenging, yet eminently do-able problems, as well as its nifty typesetting.
The Math-Greek alphabet (pdf), which we will use in class frequently.
Our DfyQ syllabus.
Wikipedia: (skim) Differential Equation.
W: (skim) Linear DE.
W: ODE.
W: SoV
W: Complex number.
W: Exponential function.
W: Exact DE.
