Question

What are hyperbolas used for?

Answer 1

Hyperbola has following properties.
1.The difference of distance from two foci is constant.
(PF' - PF = AA')

2.We define the coordinates as F(f, 0), F'(-f, 0), A(a, 0), A'(-a, 0) and P(x, y).
The equation of hyperbola is ........

Since PF' - PF = AA'
