Nonlinear differential equations are usually analyzed rather than solved and if they are solved, it is usually by numerical methods rather than explicitly.
In general, little is known about nonlinear second order differential equations , but two cases are worthy of discussion: (1) Equations with the y missing. 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 Solution: Since y is missing, set v=y'.

Nonlinear differential equations do not possess the property of super posability that is the solution is not also a solution. We can find general solutions of linear first-order differential equations and higher-order equations with constant coefficients even when we can solve a nonlinear first-order differential equation in the
17.05.2021 · We propose a quantum algorithm to solve systems of nonlinear differential equations. Using a quantum feature map encoding, we define functions as expectation values of parametrized quantum circuits.
