5- he eccentricity of a rectangular hyperbola is

Answer»

Rectangular hyperbola is a hyperbola for which the asymptotes are perpendicular, also called an equilateral hyperbola or right hyperbola.This occurs when the si-major and semi-minor axes are equal.

So, a=b

Since the eccentricity of the hyperbola is given by:

e=( (a^2 + b^2)^(1/2) ) / a

=> e=(( 2*a^2 ) ^ (1/2) ) / a

=>e = √2a / a

Hence, e= √2.
