In geometry, the kappa curve or Gutschovens curve is a two-dimensional algebraic curve resembling the Greek letter ϰ (kappa). The kappa curve was first studied by Gérard van Gutschoven around 1662. In the history of mathematics, it is remembered as one of the first examples of Isaac Barrows application of rudimentary calculus methods to determine the tangent of a curve. Isaac Newton and Johann Bernoulli continued the studies of this curve subsequently. Using the Cartesian coordinate system it can be expressed as: x^2(x^2 y^2)a^2y^2 #http://www.mathcurve.com/courbes2d/kappa/kappa.shtmlvertices 1000t from 0 to (2*PI)r 10
