hyperbola: the difference of the distances from any point on a hyperbola to each focus is constant and equal to the transverse axis 2a.
ellipse: the sum of the distances from any point on an ellipse to each focus is constant and equal to the major axis 2a.
c=√a2−b2c: distance from the center to a focus
e=ace: eccentricity; the larger the value of e, the straighter the hyperbola
properties of a hyperbola −(4x−6)2+(3y+5)2=1
