OverviewHigh Quality Content by WIKIPEDIA articles! In geometry, the lemniscate of Bernoulli is a plane curve defined from two given points F1 and F2, known as foci, at distance 2a from each other as the locus of points P so that PF1.PF2 = a2. The curve has a shape similar to the numeral 8 and to the symbol. Its name is from lemniscus, which is Latin for pendant ribbon. It is a special case of the Cassini oval and is a rational algebraic curve of degree 4. The lemniscate was first described in 1694 by Jakob Bernoulli as a modification of an ellipse, which is the locus of points for which the sum of the distances to each of two fixed focal points is a constant. A Cassini oval, by contrast, is the locus of points for which the product of these distances is constant. In the case where the curve passes through the point midway between the foci, the oval is a lemniscate of Bernoulli. Full Product DetailsAuthor: Lambert M. Surhone , Mariam T. Tennoe , Susan F.
