Let v = y'. Then the new equation satisfied by v is This is a first order differential equation. Once v is found its integration gives the function y. Example 1: Find the solution of equations to the three equations ÖThe solution of these simple nonlinear equations gave the complicated behavior that has led to the modern interest in chaos xy z dt dz xz x y dt dy y x dt dx 3 8 28 10( ) = − = − + − = − 26 Example 27 Hamiltonian Chaos The Hamiltonian for a particle in a potential for N particles – 3N degrees of freedom u ′ = f(x) y1(x). In this section we’ll consider nonlinear differential equations that are not separable to begin with, but can be solved in a similar fashion by writing their solutions in the form y = uy1, where y1 is a suitably chosen known function and u satisfies a separable equation. The given nonlinear differential equation is y'''[t]+(y[t]*y''[t])+y[t]'^2-1=0 with boundary conditions {y[0]=0,y'[0]=0 and y'[t]->1 as t->Infinity.

We know how to solve a linear algebraic equation, x= −b/a, but there are no general methods for finding the exact solutions of nonlinear algebraic equations, except for very special cases (quadratic equations are a primary example). Anonlinearalgebraicequationmayhavenosolution,onesolution,or manysolutions. In particular, a differential equation is linear if it is linear in terms of the unknown function and its derivatives, even if nonlinear in terms of the other variables appearing in it.
