Question

How to calculate the Foci w/ the following equation:
in comment box

Answer 1

\[\frac{ y^2 }{ 49} + \frac{ x^2 }{ 25 }\]

Answer 2

Your problem is not finished.

Answer 3

I got (0, +/- 2* sqrt 6 for the foci.

c^2 = 49 - 25
c^2 = 24 --> sqrt 4 * sqrt 6 ---> +/- 2* sqrt 6

Answer 4

I assume it is (y/7)^2+(x/5)^2=1.
Then, since 7>5 and coordinates with y, so foci are on the Y axis.
a=7,b=5,c=sqrt(a^2-b^2)=2sqrt(6).
So you are right, the foci are (0,2sqrt(6)) and (0,-2sqrt(6))
