Therefore, the coordinates of the foci are(– 4,0) and( 4,0), vertices are(– 5, 0) and( 5, 0).
Length of the major axis 2a is 10 units length of the minor axis 2b is 6 units and the eccentricity c / a is 4 / 5
Latus rectum is 2b 2 / a = 2( 3) 2 / 5 = 18 / 5
Hyperbola
A hyperbola is the set of all points in a plane, the difference of whose distances from two fixed points( focus) in the plane is a constant
