# Conic Sections

Conic sections are curves formed by intersecting a cone and a plane. These curves include circles, ellipses, parabolas and hyperbolas. Wolfram|Alpha can identify a conic section by its equation and can also compute the equation or other properties for a given conic section of a specified type.
