Archimedes "Failure" Plutonium <plutonium.archimedes@gmail.com> fails:

So why do you keep failing, again and again and again, by using the wrong
mass of the muon, even after I told you what your mistake was.
Archie Plutonium, it's obvious that you are failing deliberately. But why?


> On top of that, the fool plagiarized a dumb German-- Franz,

You never answered my question. If I wish to find the length of the hypotenuse
of a right triangle and I know the other two sides, do I have to invent my own
proof so that I don't plagiarize that Pythagoras guy?



So all you have to do is disprove the Dandelin Spheres proof and the following
proof by Franz/me, if you wish to prove an ellipse is not a conic section:


Some preliminaries:

Top view of the conic section and depiction of the coordinate system used 
in the proof:

              ^ x
              |
             -+- <= x=h
         .'   |   `.
        .     |     .
        |     |     |
        '     |     '      
         `.   |   .'
 y <----------+ <= x=0
             
Cone (side view):
                 .
                /|\
               / | \
              /b |  \
             /---+---' <= x = h
            /    |'   \
           /   ' |     \
          / '    |      \
x = 0 => '-------+-------\
        /    a   |        \

Proof:

r(x) = a - ((a-b)/h)x  and  d(x) = a - ((a+b)/h)x,  hence

y(x)^2 = r(x)^2 - d(x)^2 = ab - ab(2x/h - 1)^2 = ab(1 - 4(x - h/2)^2/h^2.

Hence (1/ab)y(x)^2 + (4/h^2)(x - h/2)^2 = 1  ...equation of an ellipse

>percentage for Moroney, 938 is what percent short of 945

You failed again! You used the wrong mass of the muon again!!

>AP writes: these type of posts goes away once the 26 year long stalker

>stamp, the "forever stamp"

No, you are the one writing multiple attack posts, not me. The only way your
attack posts will go away is if you decide to go away or change your attitude.
But you will continue to fail and post attack posts, because it is your nature
to fail. Birds fly, fish swim, dogs bark and Archimedes Plutonium fails.

But you are getting off topic again. We're discussing how the ellipse is
a conic section in this topic.

>CONIC SECTION IS OVAL, never an ellipse; proofs below ---- by Archimedes Plutonium

You actually have a proof the ellipse is not a conic section finally? Could you post
it here sometime? I don't see how that could be possible since I already know of two
proofs the ellipse is a conic section. This will be a major shakeup of the math
world, when there are conflicting proofs, proofs that A is B and A is not B.
