5 ημέρες πριν · A cone with elliptical cross section. The parametric equations for an elliptic cone of height h, semimajor axis a, and semiminor axis b are x = a(h-u)/hcosv (1) y = b(h-u)/hsinv (2) z = u, (3) where v in [0,2pi) and u in [0,h]. The elliptic cone is a quadratic ruled surface, and has volume V=1/3piabh.

There are four types of cones: circular, elliptical, right, and oblique. In the figure left, keep sliding the number of sides and see that as the number of triangular faces increases, the pyramid begins to look more and more like a cone. So, a cone is also a pyramid, and its fifth type is n = ∞.
Assume the cone is vertical, its axis is the z -axis and its base is an ellipse on the xy -plane, centered at (x, y, z) = (0, 0, 0), with semi-major axis a and semi-minor axis b. The equation of the base is thus. x2 a2 + y2 b2 = 1, z = 0. Let h be the height of the cone.
23 Ιουν 2024 · A graph of a typical ellipse is shown in Figure \(\PageIndex{6}\). In this figure the foci are labeled as \(F\) and \(F′\). Both are the same fixed distance from the origin, and this distance is represented by the variable \(c\).
