Over long periods of time, nonlinear differential equations can act in very strange ways. There aren’t many ways to solve nonlinear differential equations exactly, and the ones that do exist usually require the equation to have certain symmetries. Nonlinear Differential EquationĪ non-linear differential equation is one in which the unknown function and its derivatives don’t have a straight line when plotted in a graph (the linearity or non-linearity in the arguments of the function are not considered here). If the unknown function depends on more than one variable and the derivatives in the equation are partial derivatives, then the linear differential equation can also be called a linear partial differential equation. This kind of equation is called an ordinary differential equation. Where a 0 (x), …, a n (x) and b(x) are arbitrary differentiable functions that don’t have to be linear, and y′,…, y(n) are the successive derivatives of an unknown function y of the variable x. Linear Equation Differential: A differential equation that is defined by a linear polynomial in the unknown function and its derivatives is called a linear differential equation.Ī 0 (x) y + a 1 (x) y’ + a 2 (x) y’’ + … + a n (x) y n = b (x) Let’s start with the basics and learn what a linear differential equation is before moving on to the more complicated topic of a non-linear differential equation. The functions in an application typically stand in for physical quantities, the derivatives for the rates of change in those values, and the differential equation for defining the relationship between the two. This type of equation can take on many different forms. A differential equation is an equation that relates one or more unknown functions and their derivatives.
