WebEnvelope of the Family of Integral Curves and \(C\)-discriminant. Another way to find a singular solution as the envelope of the family of integral curves is based on using \(C\)-discriminant. Let \(\Phi \left( {x,y,C} \right)\) be the general solution of a differential equation \(F\left( {x,y,y'} \right) = 0.\) Graphically the equation \(\Phi ... WebJun 5, 2024 · Envelope. of a family of curves in the plane. The curve that at every point touches one of the curves of the family such that the points of contact along the envelope pass from one curve of the family to another. For example, the family of circles of the same radius with centres on a straight line has an envelope consisting of two parallel lines.
