*In mathematics , a linear differential equation is a differential equation that is defined by a linear polynomial in the unknown function and its derivatives, that is an equation of the form. This is an ordinary differential equation ODE. A linear differential equation may also be a linear partial differential equation PDE , if the unknown function depends on several variables, and the derivatives that appear in the equation are partial derivatives.*

## Nonlinear Differential Equations

In this section we compare the answers to the two main questions in differential equations for linear and nonlinear first order differential equations. Recall that for a first order linear differential equation. Recall that if a function is continuous then the integral always exists. If we are given an initial value. This immediately shows that there exists a solution to all first order linear differential equations. This also establishes uniqueness since the derivation shows that all solutions must be of the form above. This proves that the answers to both of the key questions are affirmative for first order linear differential equations.

## Nonlinear Partial Differential Equations for Scientists and Engineers

When you study differential equations, it is kind of like botany. You learn to look at an equation and classify it into a certain group. The reason is that the techniques for solving differential equations are common to these various classification groups. And sometimes you can transform an equation of one type into an equivalent equation of another type, so that you can use easier solution techniques. Here then are some of the major classifications of differential equations:.

Nonlinear Differential Equations: Invariance, Stability, and Bifurcation presents the developments in the qualitative theory of nonlinear differential equations. This book discusses the exchange of mathematical ideas in stability and bifurcation theory. Organized into 26 chapters, this book begins with an overview of the initial value problem for a nonlinear wave equation. This text then focuses on the interplay between stability exchange for a stationary solution and the appearance of bifurcating periodic orbits. Other chapters consider the development of methods for ascertaining stability and boundedness and explore the development of bifurcation and stability analysis in nonlinear models of applied sciences.

In this study,differential transform method DTM is applied to linear and nonlinear system of ordinary differential equations. If the system considered has a solution in terms of the series expansion of known functions,this powerful method catches the exact solution. So as to show this capability and robustness, some systems of ordinary differential equations are solved as numerical examples.

*There are numerous examples and the emphasis is on applications to almost all areas of science and engineering. There is truly something for everyone here. This reviewer feels that it is a very hard act to follow, and recommends it strongly.*

Differential equations are classified into linear DEs or nonlinear DEs. An nth order differential equation is said to be linear if it can be written in the form: that is, it.
