Hyperbole

Hyperbole is a set of points in the plane, where the difference of the distances of the points from two fixed points is constant. The two points are called focal points..

Hiperbola

r2-r1=2a=const

e=a2+b2

Equation of hyperbole

( x u ) 2 a 2 - ( y v ) 2 b 2 = 1

Central Hyperbole

Central Hyperbole

x 2 a 2 - y 2 b 2 = 1
