1. Hyperbola - A hyperbola is the set of all points in a plane, the difference of whose distances from two fixed points in the plane is a constant.

• The term “difference” that is used in the definition means the distance to the farther point minus the distance to the closer point.

• The two fixed points are called the foci of the hyperbola.

• The mid-point of the line segment joining the foci is called the centre of the hyperbola.

• The line through the foci is called the transverse axis and the line through the centre and perpendicular to the transverse axis is called the conjugate axis.

• The points at which the hyperbola intersects the transverse axis are called the vertices of the hyperbola.

• We denote the distance between the two foci by 2c, the distance between two vertices (the length of the transverse axis) by 2a and we define the quantity b as

$\mathrm{b}=\sqrt{c^2-a^2}$

1. Eccentricity

Eccentricity of hyperbola is same like eccentricity of ellipse, the ratio $e=\frac{c}{a}$ is called the eccentricity of the hyperbola. Since c ≥ a, the eccentricity is never less than one. In terms of the eccentricity, the foci are at a distance of ae from the centre.

1. Standard equation of Hyperbola

The equation of a hyperbola is simplest if the centre of the hyperbola is at the origin and the foci are on the x-axis or y-axis.

The equation of a hyperbola with foci on the x-axis is $\frac{x^2}{a^2}-\frac{y^2}{b^2}=1$

1. Latus rectum

Latus rectum of hyperbola is a line segment perpendicular to the transverse axis through any of the foci and whose end points lie on the hyperbola.

Length of the latus rectum of the hyperbola $\frac{x^2}{a^2}-\frac{y^2}{b^2}=1$ is $\frac{2 b^2}{a}$
