Hyperbola

Hyperbola is the locus of points where the absolute value of the difference of the distances to the two fixed points is a constant equal to 2a, the distance between its two vertices.

F1, F2 - fixed points: foci or focal points of the hyperbola

A, B - vertices of the hyperbola

S - center of the hyperbola

2a=|AB| - transverse or major axis

2b=|CD| - conjugate or minor axis

e - linear eccentricity

e2 = a2 + b2

r1, r2 - radial vectors of the point T
