Эллипсоид. Неравносторонний эллипсоид
Эллипсоид - одна из геометрических фигур, в которой поверхность напоминает сферу, в которой сечение похоже на эллипс.
Формула для обычного эллипсоида в 3-х мерной системе:
где a, b, c - радиусы по осям x, y, z соответственно..
Объем обычного эллипсоида можно посчитать по данной формуле:
А вот площадь поверхности не равностороннего эллипсоида сложно представить с помощью простых функций. Математик из Дании, Кнуд Томсен, предложил следующий вариант вычисления:
где p=1.6075
