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.
A hyperbola comprises two disconnected curves called its arms or branches which separate the foci. At large distances from the foci the hyperbola begins to approximate two lines, known as asymptotes. The asymptotes cross at the center of the hyperbola and have slope \pm \frac for an East-West opening hyperbola or \pm \frac for a North-South opening hyperbola.
