In mathematics, a hyperbola (plural hyperbolas or hyperbolae) is a type of smooth curve, lying in a plane, defined by its geometric properties or by equations for which it is the solution set. A hyperbola is a curve where the distances of any point from: a fixed point (the focus), and. a fixed straight line (the directrix) are always in the same ratio. This ratio is called the eccentricity, and for a hyperbola it is always greater than 1.
This ratio is called the eccentricity, and for a hyperbola it is always greater than 1. The hyperbola is an open curve (has no ends). But that isn't the full story! Because a hyperbola is actually two separate curves in mirror image like this: On the diagram you can see: 1  a directrix and a focus (one on each side)  an axis of symmetry (that goes through each focus, at right angles to the directrix)
