| http://www.w3.org/ns/prov#value | - Let us now consider a Simple Differential Equation of the second order: such for instance as is given by this problem, ``To find the curve in which the radius of curvature is a function, given in form, of the ordinate.'' here the algebraic solution gives a formula requiring two undetermined quantities, still simple constants: the equivalent geometrical treatment shews that we require two e
