Fundamentals of Differential Eqns with Boundary
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

from a classmate, or several.
All my classes have a
Material to learn
- The gentle
(on Wedn., 04Apr2018),
not ask students to compute
which, anyway, equals
The Laplace transform (pdf)
has an example, a simplification of tapping on a bell.
Also available is a small
Table of Laplace transforms (pdf).
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).
- With its Salty language,
(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
(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
degree-N homogeneous polynomial
in its N2 many entries (txt).
The various DiffyQ czars who helped out.
||Um ... oh yeah, Zorana!
