Summary

[edit]
Description
English: Sections of ellipsoid with semi-axes a=8, b=6, c=4.82≈6.8 by planes containing Oz axis. We see, that when the angle t of the plane with Ox axis is 45 or 135 degrees, then we have circles (in blue). Otherwise we have ellipses with eccentricity gradually changing between 0 and eccentricities of sections by yz and xz planes (in yellow).
Русский: Сечения эллипсоида с полуосями a=8, b=6, c=4.82≈6.8 плоскостями, содержащими ось Oz. Мы видим, что когда угол t секущей плоскости с осью Ox равен 45 или 135 градусам, в сечении получаем окружности (выделены синим). В других случаях получаем эллипсы с эксцентриситетом, постепенно меняющимся между 0 и эксцентриситетами сечений эллипсоида плоскостями yz и xz (выделены жёлтым).
