In each of the, find the coordinates of the foci and the vertices, the eccentricity and the length of the latus rectum of the hyperbolas.
5y2 – 9x2 = 36
The given equation is 5y2 – 9x2 = 36
We can re-write the given as
Or
……….. (1)
On comparing this equation (1) with the standard equation of hyperbola
, we get,
a =
and b =2
We know, a2 + b2 = c2
Thus,
c2 =
= ![]()
⇒ c = ![]()
Therefore,
The coordinates of the foci are ![]()
The coordinates of the vertices are
.
Eccentricity, e = 
Length of latus rectum = ![]()
