foci x^2+9y^2=9

Solution

foci

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

Solution

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

Solution steps

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

Calculate ellipse properties

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

Ellipse with center

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

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

Compute

c :

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

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

Refine

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

Popular Examples

vertices (x^2)/(49)-(y^2)/(16)=1 vertices

\frac{x ^{2}}{49} - \frac{y ^{2}}{16} = 1

foci (x^2}{16}+\frac{y^2)/9 =1 foci

\frac{x ^{2}}{16} + \frac{y ^{2}}{9} = 1

x = - \frac{1}{8} y^{2}

y^{2} = - 32 x

x^{2} - 6 x + 5 y = - 34
