Summary[edit]
| Description |
English: Sections of ellipsoid with semi-axes a=8, b=6, c=4.8√2≈6.8 by planes parallel to Oz axis and inclined at an angle of 45 degrees to Ox axis. We see, that all of them are circles of radius r. Absolute value of k is the distance from the plane to the point (0,0,0). A center of each circle is marked with a blue point. These centers lie on a line (blue), which, containing (0,0,0) point and lying on xy plane, is inclined to the direction of the secant plane movement. Русский: Сечения эллипсоида с полуосями a=8, b=6, c=4.8√2≈6.8 плоскостями, параллельными оси Oz и наклонёнными к оси Ox на угол 45 градусов. Мы видим, что все они — окружности радиуса r. Модуль k — расстояние от секущей плоскости до точки (0,0,0). Центр каждой окружности обозначен синей точкой. Эти центры лежат на одной линии (синяя), которая содержит точку (0,0,0) и принадлежит плоскости xy, но наклонена по отношению к направлению движения секущей плоскости. Такие круглые сечения можно найти у любого эллипсоида с неравными полуосями, так как значение одной из полуосей лежит между двумя другими, и эту полуось можно обозначить c. |
