Line 34: The lemniscate :<math>(x^2+y^2)^2=x^2-y^2</math> consists of the points such that the product of their distances from two the two points (√2, 0), (−√2, 0) is the constant 1/2. The length ''r'' of the arc from the origin to a point at distance ''s'' from the origin is given by :<math> r=\int_0^s\frac{dt}{\sqrt{1-t^4}}</math> ==See also==
