Question
Find the co-ordinates of foci, the vertices, the length of transverse axis, the length of conjugate axis, the eccentricity, the latus rectum of the hyperbola:
Solution
The hyperbola is : which is of the form
∴ Its foci and vertices lie on x-axis.
The foci are :
The vertices are:
The length of transverse axis = 2a = 2 x 4 = 8
The length of conjugate axis = 2b = 2 x 3 = 6
Let the eccentricity be e. We know that c = ae
5 = 4e
Length of latus rectum =
