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 12 DfyQ quizzes so far (pdf). [Monday, 26Nov2018]
Algorithms for solving some differential equations (pdf) [DiffyNotes]. [Tuesday, 13Nov2018] [I'll use this for class lectures. Our textbook will be used for reading assigments and as a problem-reservoir.]
Popular was the short Class-U with its delightful two-column layout.
Folks breezed through the aptly-titled Class-T and also learned of the Robert Long Prize essay competition.
Folks were delighted with the nifty Class-S and its quick True-False question.
Wikipedia: W: SoV W: ODE.
W: Complex number. W: (skim) Linear DE. W: Exponential function.
W:(skim) Differential Eqn.
Our DfyQ syllabus.
Read eventually: W: FTODE, Picard-Lindelof theorem.
You have learned the Math-Greek alphabet (pdf), which we will use in class frequently.
At home, please use 80 minutes take this Sample exam of prerequisite knowledge (pdf). Then use your Calculus text to grade yourself. This will help you know what you need to review.

Textbook: Fundamentals of Differential Eqns with Boundary Value Problems, (9^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.

Tacoma Narrows collapse and W:Tacoma Narrows Bridge and TNB People 2 (Hallett R. French), and the claim about Dexter R. Smith. Also TNB People 1.

The Individual Optional Project IOP-V

...will be due slid u n d e r room 402 Little Hall my office door (Little Hall 402, Northeast corner) , by 2PM, Thursday, 06Dec2018.

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.
