foci 9x^2+7y^2=63

Solution

foci

9 x^{2} + 7 y^{2} = 63

Solution

(0, 2), (0, - 2)

Solution steps

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

Calculate ellipse properties

9 x^{2} + 7 y^{2} = 63 :

Ellipse with center

(h, k) = (0, 0), b = 3, a = 7

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

Compute

c :

c = 3^{2} - 7^{2} : 2

(0, 0 + 2), (0, 0 - 2)

Refine

(0, 2), (0, - 2)

Popular Examples

foci ((x-3)^2)/(64)+((y+1)^2)/(49)=1 foci

\frac{( x - 3 ) ^{2}}{64} + \frac{( y + 1 ) ^{2}}{49} = 1

foci ((x+20)^2)/(16)+(y^2)/(89)=1 foci

\frac{( x + 20 ) ^{2}}{16} + \frac{y ^{2}}{89} = 1

foci (x^2)/(9/4)+(y^2)/(25/4)=1 foci

\frac{x ^{2}}{\frac{9}{4}} + \frac{y ^{2}}{\frac{25}{4}} = 1

foci ((x-3)^2}{25}+\frac{(y-3)^2)/4 =1 foci

\frac{( x - 3 ) ^{2}}{25} + \frac{( y - 3 ) ^{2}}{4} = 1

foci ((x-3)^2}{25}+\frac{(y+3)^2)/4 =1 foci

\frac{( x - 3 ) ^{2}}{25} + \frac{( y + 3 ) ^{2}}{4} = 1
