Find the equation of the hyperbola whose foci are (0, ±13) and the length of whose conjugate axis is 24.
Given: Foci are (0, ±13), the conjugate axis is of the length 24
Need to find: The equation of the hyperbola.
Let, the equation of the hyperbola be:
The conjugate axis is of the length 24, i.e., 2b = 24
Therefore, b = 12
The foci are given at (0, ±13)
A and B are the foci.
That means, ae = 13, where e is the eccentricity.
We know that,
Therefore,
⇒
⇒
⇒ [Squaring both sides]
⇒ [As b = 12]
So, the equation of the hyperbola is,
⇒
