Which symbol is represented by a figure 8 on its side, known as a lemniscate?
Infinity symbol Infinity symbol The infinity symbol (sometimes called the lemniscate) is a mathematical symbol representing the concept of infinity. The shape of a sideways figure eight has a long pedigree; for instance, it appears in the cross of Saint Boniface, wrapped around the bars of a Latin cross. However, John Wallis is credited with introducing the infinity symbol with its mathematical meaning in 1655, in his "De sectionibus conicis". Wallis did not explain his choice of this symbol, but it has been conjectured to be a variant form of a Roman numeral for 1,000 (originally CIƆ, also CƆ), which was sometimes
Lemniscate of Gerono Its equation is Lemniscate of Gerono In algebraic geometry, the lemniscate of Gerono, or lemniscate of Huygens, or figure-eight curve, is a plane algebraic curve of degree four and genus zero and is a lemniscate curve shaped like an formula_1 symbol, or figure eight. It has equation It was studied by Camille-Christophe Gerono. Because the curve is of genus zero, it can be parametrized by rational functions; one means of doing that is Another representation is which reveals that this lemniscate is a special case of a Lissajous figure. The dual curve (see Plücker formula), pictured below, has therefore a
