Differentiating. the general solution of the homogeneous equation (1.9), and add to this a particular solution of the inhomogeneous equation (check that the di erence of any two solutions of the inhomogeneous equation is a solution of the homogeneous equation). For solving the equation we use an auxiliary variable p = : d ⁢ y d ⁢ x and write (1) as y = p ⁢ x + ψ ⁢ ( p ) . Now the clairaut’s equations becomes. For first-order partial differential equations in two independent variables, an exact solution (*) w = Φ(x, y, C 1, C 2) that depends on two arbitrary constants C 1 and C 2 is called a complete integral. Taking one more differentiation leads to Therefore, the left-hand side of the equation will always be greater than, or equal to one and thus cannot be zero and hence the differential equation is not satisfied. everywhere. Learn with content. that cannot be obtained by specialising the arbitrary constants. If we manage to integrate it and to find its general solution p = ϕ (y ,C 1) then we have dy dx = ϕ (y,C 1) and therefore the general solution of equation (3) can be directly written in the form ∫ dy ϕ (y ,C 1) = x + C 2. Hence, either 1. d2ydx2=0 or 1. x+f′(dydx)=0.
