Find the equation for the ellipse that satisfies the given conditions: Vertices (0, ± 13), Foci (0, ± 5)
Solution:
Vertices (0, ± 13), Foci (0, ± 5)
Here, the vertices are on the x-axis.
Therefore,
the equation of the ellipse will be of the form x2/b2 + y2/a2 = 1 where a is the semi major axis.
Accordingly, a = 13 and c = 5
It is known that a2 = b2 + c2
Hence,
⇒ 132 = b2 + 52
⇒ 169 = b2 + 25
⇒ b2 = 169 - 25
⇒ b2 = 144
⇒ b = 12
Thus, the equation of the ellipse is x2/122 + y2/132 = 1 or x2/144 + y2/169 = 1
