Question
Find the equation of the hyperbola satisfying the given condition.
Foci and the latus rectum is of length 12.
Solution
The foci are of the hyperbola lie on the y-axis.
∴ The standard equation of the hyperbola is: ...(i)
The foci are
Also, the latus rectum is ...(ii)
Now, (∵ )
(∵ a = -8 is not possible)
Also,
Hence, from (i), the equation of the hyperbola is or .
