Best ResponseYou've already chosen the best response.1I think it's a elliptic paraboloid but I am not sure...

Best ResponseYou've already chosen the best response.1Just looking at the cross sections.

Best ResponseYou've already chosen the best response.1I think it's the bottom left one.

Best ResponseYou've already chosen the best response.1\[x^2+z^2 = sphere\]

Best ResponseYou've already chosen the best response.1Really? Isn't x^2+y^2+z^2= r a sphere?

nincompoop

Best ResponseYou've already chosen the best response.1you need y^2 for sphere

Best ResponseYou've already chosen the best response.1would it just be a cylinder

Dido525

Best ResponseYou've already chosen the best response.1No. The cross sections are parabolas so there is no way it's a cylinder.

Best ResponseYou've already chosen the best response.0\[x^2+z^2 = 7\] is a circle :)

Best ResponseYou've already chosen the best response.1I know but... ;_; ... I thought the cross sections would be parabolas :/ .

Best ResponseYou've already chosen the best response.1which is again why i am not sure if it is the bottom left or the bottom right

Dido525

Best ResponseYou've already chosen the best response.1K, so it the the bottom right apparantly : / .

Best ResponseYou've already chosen the best response.1Because it's not like with translate the circle.

Best ResponseYou've already chosen the best response.1i guess since its missing the \(y^2\)

Best ResponseYou've already chosen the best response.1why not two parabolas?

Best ResponseYou've already chosen the best response.1you mean a hyperbola? lol

Dido525

Best ResponseYou've already chosen the best response.1It cannot be a hyperbola. No subtraction term appears.

Best ResponseYou've already chosen the best response.1wow I suck at "surface" geometry LOL so it is a circle yes? why not pick the one with a circle in the first place?

Dido525
 2 years ago
Best ResponseYou've already chosen the best response.1Because I assumed the cross sections would be parabolas so it did not seem logical to pick a cylinder :/ .

Best ResponseYou've already chosen the best response.1hey wouldnt it have to be x^2+y^2=7 to be parabolic? i think thats why its a cylinder

Dido525

Best ResponseYou've already chosen the best response.1Well if I take z=0 then we get x^2=7 which is a parabola.

some_someone

Best ResponseYou've already chosen the best response.0well x^2+y^2=7 is a circle.

Best ResponseYou've already chosen the best response.1nawwww… even if you drew just a 2D circle, in microscopic view it is still "cylindrical" in shape

Best ResponseYou've already chosen the best response.1Well I DO AGREE it is indeed a circle about the xz axis but how does that make it a cylinder? :/ .

Best ResponseYou've already chosen the best response.0Cylindrical coordinates are a generalization of twodimensional polar coordinates to three dimensions by superposing a height (z) axis. Unfortunately, there are a number of different notations used for the other two coordinates. Either r or rho is used to refer to the radial coordinate and either phi or theta to the azimuthal coordinates. Arfken, for instance, uses (rho, phi, z), while Beyer uses (r, theta, z). In this work, the notation (r, theta, z) is used. The following table summarizes notational conventions used by a number of authors.
