witch of Ag·ne·si (än-y  z )n. A planar cubic curve that is symmetric about the y-axis and that approaches the x-axis as an asymptote. Its equation is x2y = 4a2(2a - y), where a is a constant. [witch (translation of Italian avversiera, versiera, confused with versiera, curve, turning, from New Latin vers  ria, from Latin versus, turned, reversed, past participle of vertere, to turn; see verse1) + Maria Gaetana Agnesi (1718-1799), Italian mathematician.] |   MX : MY = ON : OM |

n
(Mathematics) Maths a plane curve, symmetrical about the y-axis, having the equation x2y = 4a2(2a-y) Sometimes shortened to witch
[named after Maria Gaetana Agnesi (1718-99), Italian mathematician and philosopher; probably so called from the resemblance of the curve to the outline of a witch's hat]
