Kibo, was Dr. Hanlon demoted from teaching math at Dartmouth for the fool just cannot understand geometry, the slant cut is never a ellipse. And that also cascades into Dr. Hanlon never able to even recognize Calculus with a geometry proof of Fundamental Theorem of Calculus, but Dartmouth is kind hearted and gave him job as president of Dartmouth, for they did not want to see him out on the streets as a hobo.

Kibo Parry M on Dartmouth's Dr.Hanlon, Stanford's Marc Tessier-Lavigne,Ruth Charney & Andrew Wiles too stupid to see the cylinder gives a ellipse but cone gives a oval, never ellipse. Are they more stupid than you Kibo with your 938 is 12% short of 945 in math?

Kibo why is Dartmouth's Dr.Hanlon, Stanford's Marc Tessier-Lavigne,Ruth Charney & Andrew Wiles too stupid to see the cylinder gives a ellipse but cone gives a oval, never ellipse. Are they more stupid than you Zelos in math?

--- quoting from AP's 68th book of science ---
ARRAY, Analytic Geometry Proof, Cylinder Section is a Ellipse::
 
 
                E
               __
        .-'              `-.
      .'                    `.
    /                         \
   ;                           ;
  | G          c              | H
   ;                           ;
    \                         /
     `.                     .'
        `-.    _____  .-'
                  F
 

Alright, focus on the distance from c to F in the cone-cut compared to the distance from c to E

In a Cylinder cut, those two distances are the same because a cylinder has two axes of symmetry.

The side view of a cylinder is this

|    |
|    |
|    |

That allows cE to be the same distance as cF

But the side view of the cone is

     /\E
    /c \
F /     \

The distance c to E is shorter because the slant of the side walls of the cone are in the direction of shortening cE, whereas the slant opposite c in cF makes that distance larger than cE.
