Oh we're *so* surprised, some geekwad from sci.physics crossposts a 
reply to bitch about crossposting, adding to the issue as he talks about 
having a license to post, full of his esoteric rules he would dictate to 
everyone.  You should really lose your virginity.

Yes.  Now try the following.  Both expressions are equal.  Reduce one
to the other:

1)

 ⎛                   _______________⎞
 ⎜  _         2     ╱              2⎟
 ⎜╲╱3 ⋅ sin(t)  ⋅ ╲╱ 4 - 3 ⋅ sin(t) ⎟
-⎜──────────────────────────────────⎟
 ⎜             4             2      ⎟
 ⎝   9 ⋅ cos(t)  + 6 ⋅ cos(t)  + 1  ⎠



2)

   _         2     _
 ╲╱3 ⋅ cos(t)  - ╲╱3
────────────────────
                 ⎛3⎞
                 ⎜─⎟
                 ⎝2⎠
⎛          2    ⎞   
⎝3 ⋅ cos(t)  + 1⎠



Again, these are another component of the 2 vectors produced by
Maxima.  The vectors are equal but Maxima has simplified each
differently.  But Maxima cannot reduce one to the other, at least
not with the default procedures.

For some reason, #2 did not print properly.  The numerator should
be:

sqrt(3) * cos(t)^2 - sqrt(3)

Nobody *here* cares about that.  FOAD.

On my screen it is properly printed.

Uploaded any of those videos of yours recently? :)

To me the term looks like

  [√(3) cos(t)^2 - √(3)]/[3 cos^(t)^2 + 1]^(3/2),

but only if I use DejaVu Sans Mono 13pt (not, for example, with Consolas
12pt, another monospace font).

So this is more evidence that it is not a good idea (that should even
convince the staunchest supporter) to *draw* equations (using Unicode) in
Usenet.  [As you can see, I can find nothing wrong with *writing* Unicode
characters when using ASCII would be clumsy instead.]

This one befits a math head better:

An Iranian Ayatollah invites a penniless Iranian scientist to give him a 
visit. When the scientist visits him, he goes like:

Ayatollah: We gave this question to every engineer we could and none of 
them could answer it. Fat, thin, short, tall, rich, or super rich, 
didn't matter. None of those donkeys could answer it. Then someone said 
why not asking a scientist, so now you're here.

Scientist: What is the question?

Ayatollah: I have gathered fund to distribute a large number of spies 
throughout occupied Palestine (Israel.) All of them are non-Iranian, and 
have different ethnicity. We have divided up the entire land into as 
many zones as we plan to assign spies to. The spies will only contact 
each other if they're stationed in neighboring zones. But we do not want 
any spy have a neighboring spy of the same ethnicity.

Scientist: !.. Why not?

Ayatollah: Because if of the same ethnicity, their stupid wives will be 
talking each other's brains on the phone all day and Mossad can easily 
get suspicious of the two households.

Scientist: Oh!..

Ayatollah: So here's the problem we have. We prefer to use as few 
different ethnicity among the spies as possible. So what is the minimum 
number of different ethnicity we can limit our process to, to distribute 
them in a way to prevent any neighboring spies of same ethnicity?

And he continues:

Ayatollah: So are we done here?

Scientist: Of course not. What's in it for me? I'm not one of your 5 
million Basij slave to do it free for you.

Ayatollah: Hmm.. how about ... much in advance and another ... much 
after you come up with the answer?

The scientist takes out his smartphone and uses the astronomical number 
to convert the amount into U.S. dollar, and then:

Scientist: Holy fucking shit.. I'm in it!

So he gets the first payment and goes home, works on the problem for a 
day, and goes back and gives the answer to the Ayatollah and gets the 
final payment.

What was his answer?
