Фокусы Эллипса

Для эллипса с большой осью, параллельной оси y, Фокусы (точки фокуса) определяются как (h, k+c), (h, k−c),
, где c=√b²−a² является расстоянием от центра (h, k) к фокусу

(h, k+c), (h, k−c)

Вычислите свойства эллипса

9x²+4y²=36: Эллипс с центром (h, k)=(0, 0), b=3, a=2

(0, 0+c), (0, 0−c)

Вычислите c:

c=√3²−2²: √5

(0, 0+√5), (0, 0−√5)

Уточнить

(0, √5), (0, −√5)
