foci x^2+16y^2=16

Solution

foci

x^{2} + 16 y^{2} = 16

Solution

(15, 0), (- 15, 0)

Solution steps

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

Calculate ellipse properties

x^{2} + 16 y^{2} = 16 :

Ellipse with center

(h, k) = (0, 0), a = 4, b = 1

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

Compute

c :

c = 4^{2} - 1^{2} : 15

(0 + 15, 0), (0 - 15, 0)

Refine

(15, 0), (- 15, 0)

Popular Examples

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

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

foci 25x^2+4y^2=100 foci

25 x^{2} + 4 y^{2} = 100

foci 9x^2+36y^2+36x+432y=-1008 foci

9 x^{2} + 36 y^{2} + 36 x + 432 y = - 1008

foci 4x^2+9y^2-32x-36y+64=0 foci

4 x^{2} + 9 y^{2} - 32 x - 36 y + 64 = 0

foci 4x^2+y^2=4 foci

4 x^{2} + y^{2} = 4
