Circles, Parabolas, Ellipses, and Hyperbolas with complete solutions |graded A+
Circle Collection of points equidistant from the center. Equations for Circle (x-h)^2 + (y-k)^2 = r^2 Where (h,k) = center And r = radius 00:24 01:28 Distance Formula The square root of (x2-x1)^2 + (y2-y1)^2 Parabola Set of points equidistant from a focus and the directrix. Equations for Parabolas (x-h)^2 = 4p(y-k) Up if p0, down if p0 (y-k)^2 = 4p(x-h) Right if p0, left if p0 p = distance (h,k) = vertex Directrix Equation of a line. Either y=? or x=? Eccentricity Measures the ovalness of an ellipse. e = c/a Ellipse Set of all points that the sum of the distances from the foci to those points is the same.
