The Laplace transform (pdf)
has an example, a simplification of tapping on a bell.
Also available is a small
Table of Laplace transforms (pdf).
- Algorithms for solving some differential equations (pdf)
Please read the beginning of the convolution
through Example C3, convolution of exponentials.
Available are all the
quizzes so far (pdf).
Flowers and gold coins were tossed on the stage
by an appreciative audience for Class-Y (pdf).
Admittedly, Act II had that challenging VoP scene; a resolution is
in the above playbill.

Headline news from coast to coast:
[The PDF has some solns.]
One reviewer opined:
With its clean two-tone format, crisp type-setting,
and straightforward problems, it is a model for exams everywhere.
Crowds cheered, when discovering that the fascinating
was all short-answer. This PDF now has solns to all of its DE problems.
Have solidly learned the
Math-Greek alphabet (pdf).

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
