Parametric Equations of Ellipses and Hyperbolas. The normal form of a parabola is the following implicit equation: In this normal form, for any point (x,y) on a parabola, the value of y must be positive and the opening of this parabola is upward. representations can make solving certain problems easier (for example, most of the sketches using a computer I do using parametric representations). Parabolic cylinder functions (PCFs) U(a,z), V(a,z), and W(a,z) are associated with the parabolic cylinder in harmonic analysis; therefore, their descriptions can be found everywhere [38, 46,48 49. Parabola definition is - a plane curve generated by a point moving so that its distance from a fixed point is equal to its distance from a fixed line : the intersection of a right circular cone with a plane parallel to an element of the cone.
