## Definition Of Hyperbola

Hyperbola is a conic section in which difference of distances of all the points from two fixed points (called foci) is constant.

The general equation for hyperbola is .
The eccentricity (e) of a hyperbola is always greater than 1, e > 1.
The slope of asymptotes for both horizontal and vertical hyperbola is .

The equation for the horizontal hyperbola is .
