Trouble with DSolve[ ], by Dave Vasholz

ABSTRACT.   Here I discuss a very simple differential equation which =
Wolfram Tech Support acknowledges is completely flubbed by our beloved
software. It is further shown how, in the end, Mathematica can be used =
recover from its own folly.

Confirming and Generating Probability Density Functions of Two Random
Variables With Mathematica, by Mel Friedman

ABSTRACT.  Given continuous random variables X and Y having known
probability density functions, let W = g(X,Y) and Z = h(X,Y), where =
g and h
are known.  Here we use Mathematica to find the density functions of W, =
and W*Z.  We also show how to use Mathematica to confirm the correctness =
the analytical results by simulation.
