### parabola

(Learning Modules / Mathematics / Modelling projectiles) The form of a graph in which the vertical increment changes as the square of the horizontal increment.

The line perpendicular to the directrix and passing through the focus (that is, the line that splits the parabola through the middle) is called the `axis of symmetry`. The point on the axis of symmetry that intersects the parabola is called the `vertex`, and it is the point where the curvature is greatest. The distance between the vertex and t...

• (n.) One of a group of curves defined by the equation y = axn where n is a positive whole number or a positive fraction. For the cubical parabola n = 3; for the semicubical parabola n = /. See under Cubical, and Semicubical. The parabolas have infinite branches, but no rectilineal asymptotes. • (n.) A kind of curve; one of the conic sec...

A curve, with an eccentricity equal to 1, obtained by slicing a cone with a plane parallel to one side of the cone. A parabola can be considered an ellipse with an infinite major axis. It is one of the types of conic section. One of the most studied curves in the history of mathematics, a parabola ...
