Hi, Philippe, and thanks for your response. The answer to your
question is because that was the condition posed by a certain
mathematical problem I ran across on the sci.math site some time ago.
It had to do with a square, but I expanded it to include rectangles of
any aspect ratio. I solved the new problem to my satisfaction, but

Rather than a cavity, the region is one of zero gravity!
The pressure assures that nucleii are closest to one anotther there. Fusion
could be self-regulating... If it gets too hot, the core expands, moderation
occurs and the fusion slows, etc. No thermostat required.
The vacuum concept is the one that does not occur, per se. In its place is

Hi,
Why do you restrict your problem of "radiused corners", if I correctly
understand what you mean by that, to rectangles ?

Is there a name given to the problem of finding the maximum area-to-
perimeter ratio of a rectangle having radiused corners?

But if you can already prove the given statement false by citing a
specific counterexample, there is no need for anything further.

Well all of the other problems in this section use the regular trig
functions and trigonometric identities to get rid of the inverse functions
in order to develop the solution. Sort of like getting rid of arcsin x by
taking sin (arcsin x) to obtain x.

Here it is, then. All the roots to any power series.

What leads you to suppose that the left hand side can be made any
simpler that it already is?

Here is a true or false problem:
(arcsin x)**2 + (arccos x)**2 = 1
I know that this is false and can prove it via a specific example, say with
x = 0.5
However I seem to be unable to come up with a generalized expression for the
left hand side of the equation that would also show that it is false. How

Which game has more possibilities, stratego or chess ?

Hello,
I am wondering which game has more possibilities for a computer to
calculate:
1. Stratego
or
2. Chess
?
For stratego:
Calculation possibility 1: assume all setups are known in advance and
visible/open playing field.
Calculation possibility 2: setups are hidden try guessing, only one side is
