Hyperbola:
left & right
Hyperbola:
• a hyperbola is the set of all points in a plane such that the difference between the distances from a point on the graph to two fixed points is a given constant
Asymptotes:
difference of focal radii is • each of the fixed points is a focus
• if a point is on the hyperbola, then the distance between that point and the foci is the focal radii
• the two lines that the hyperbola approaches are the asymptotes of the hyperbola
