PARABOLAS F(x) = a(x-h)^2 + k A parabola is the locus of all points in a given plane that are the same distance from a given point, called the focus, and a given line, called the directrix. Car Headlights:

CIRCLES (x-h)^2 + (y-k)^2 = r^2 A circle is the locus of all points in a plane at a given distance, called the radius, from a fixed point on the plane, called the center. Mushroom Tops (Nature):

ELLIPSES [(x-h)^2/a^2] + [(y-k)^2/b^2] = 1 An ellipse is the locus of all points in a plan such that the sum of the distances from two given points in the plane, called the foci, is constant. Tycho Brahe Planetarium in Copenhagen (Architecture):

Hyperbolas [(x-h)/a^2 â€“ (y-k)/b^2] = 1 A hyperbola is the locus of all points in the plane such that the absolute value of the difference of the distances from two given points in the plane, called the foci, is constant.
