foci x^2+9y^2=36

Solution

foci

x^{2} + 9 y^{2} = 36

Solution

(42, 0), (- 42, 0)

Solution steps

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

Calculate ellipse properties

x^{2} + 9 y^{2} = 36 :

Ellipse with center

(h, k) = (0, 0), a = 6, b = 2

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

Compute

c :

c = 6^{2} - 2^{2} : 42

(0 + 42, 0), (0 - 42, 0)

Refine

(42, 0), (- 42, 0)

Popular Examples

foci 9x^2+25y^2+108x-200y+499=0 foci

9 x^{2} + 25 y^{2} + 108 x - 200 y + 499 = 0

foci ((x-6)^2)/(49)+((y-6)^2)/(36)=1 foci

\frac{( x - 6 ) ^{2}}{49} + \frac{( y - 6 ) ^{2}}{36} = 1

foci 8x^2+4y^2+16x-12y-15=0 foci

8 x^{2} + 4 y^{2} + 16 x - 12 y - 15 = 0

foci (25x^2)/4-50x+100y^2+800y+1075=0 foci

\frac{25 x ^{2}}{4} - 50 x + 100 y^{2} + 800 y + 1075 = 0

foci 5x^2+y^2=5 foci

5 x^{2} + y^{2} = 5
