WebA Clairaut equation is a first-order equation of the form A remarkable feature of this nonlinear equation is that its general solution has a very simple form. This is an example of a Clairaut equation: In [48]:= Out [48]= The general solution to Clairaut equations is simply a family of straight lines. WebIf the PDE is nonlinear, a very useful solution is given by the complete integral. This is a function of u ( x, y, C [ 1], C [ 2]), where C [ 1] and C [ 2] are independent parameters and u satisfies the PDE for all values of ( C [ 1], C [ 2]) in an open subset of the plane.
