foci 9x^2+y^2=9

Solution

foci

9 x^{2} + y^{2} = 9

Solution

(0, 22), (0, - 22)

Solution steps

(h, k + c), (h, k - c)

Calculate ellipse properties

9 x^{2} + y^{2} = 9 :

Ellipse with center

(h, k) = (0, 0), b = 3, a = 1

(0, 0 + c), (0, 0 - c)

Compute

c :

c = 3^{2} - 1^{2} : 22

(0, 0 + 22), (0, 0 - 22)

Refine

(0, 22), (0, - 22)

Popular Examples

vertices (x^2)/4-(y^2)/(16)=1 vertices

\frac{x ^{2}}{4} - \frac{y ^{2}}{16} = 1

vertices f(x)=x^2+4x-5 vertices

f (x) = x^{2} + 4 x - 5

vertices x^2+9y^2+6x-90y+225=0 vertices

x^{2} + 9 y^{2} + 6 x - 90 y + 225 = 0

(x^2}{25}-\frac{y^2)/9 =1

\frac{x ^{2}}{25} - \frac{y ^{2}}{9} = 1

(x^2}{49}+\frac{y^2)/9 =1

\frac{x ^{2}}{49} + \frac{y ^{2}}{9} = 1
