Singular solution uniqueness if a solution of the first form intersects the second solution. The condition of intersection is : "y"("x") = "y"("x"). We solve to find the intersection point, which is formula_41. We can verify that the curves are tangent at this point "y'"("x") = "y'"("x"). We calculate the derivatives: Hence, is tangent to every member of the one-parameter family of solutions of this Clairaut equation: Singular solution A singular solution "y"("x") of an ordinary differential equation is a solution that is singular or one for which the initial value problem (also called the Cauchy problem by some authors) fails to
