DiffyQ

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). [Why?]
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 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).
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.
Read eventually: W: FTODE, Picard-Lindelof theorem.
Examples illustrating Det(N×N matrix) is a degree-N homogeneous polynomial in its N² many entries (txt).
