Question

What is Hyperbola?

Answer

Hyperbola is a curve of conic family with eccentricity greater than 1. It is the focus of a point which moves so that the ratio of its distance from a fixed point to its distance from a fixed line is a constant greater than 1. It can be represented by the equation $\frac{x^2}{a^2}\mathrm{-}\frac{y^2}{b^2}=1.\mathrm{ It\; has\; two\; foci.}$
