A differential equation that can be written in the form M(x,y)dx+N(x,y)dy=0 where M ( tx, ty) = t n M(x,y) and N(tx, ty ) = t n N (x, y ) is called a homogeneous differential equation of degree n. A differential equation that can be written in the form M(x,y)dx+N(x,y)dy=0 where ôNôX = δMδY is called an exact differential equation. Description. Differential Equations with Mathematica presents an introduction and discussion of topics typically covered in an undergraduate course in ordinary differential equations as well as some supplementary topics such as Laplace transforms, Fourier series, and partial differential equations. 10.5.1 Laplace's Equation in a Circular Region 817 10.5.2 The Wave Equation in a Circular Region 821 10.5.3 Other Partial Differential Equations 836 Appendix: Getting Started 841 Introduction to Mathematica 841 A Note Regarding Different Versions of Mathematica 843 Getting Started with Mathematica 843 A Real and Linearized Pendulum. When simulating the motion of a pendulum the true equation is one which is not solvable exactly as it is nonlinear (for a unit mass it is y”+d y’+k sin (y) =0, where y is the angle of the pendulum, d is a friction constant, and k is a “spring constant” related to the length of the pendulum and gravity).
Use diff and == to represent differential equations. For example, diff(y,x) == y represents the equation dy/dx = y.

The Mathematica function DSolve finds symbolic solutions to differential equations. (The Mathe-matica function NDSolve, on the other hand, is a general numerical differential equation solver.) DSolve can handle the following types of equations: † Ordinary Differential Equations (ODEs), in which there is a single independent variable t and First, solve the differential equation using DSolve and set the result to solution: Use = , /. , and Part to define a function g [ x ] using solution : Define a table of functions t [ x ] for integer values of C [ 1 ] between 1 and 10: Mathematica's diversity makes it particularly well suited to performing calculations encountered when solving many ordinary and partial differential equations. In some cases, Mathematica's built-in functions can immediately solve a differential equation by providing an explicit, implicit, or numerical solution.
The purpose of Differential Equations with Mathematica, Fourth Edition, is twofold. First, we introduce and discuss the topics covered in typical undergraduate and beginning graduate courses in ordinary and partial differential equations including topics such as Laplace transforms, Fourier series, eigenvalue problems, and boundary-value problems.

Automatically selecting between hundreds of powerful and in many cases original algorithms, the Wolfram Language provides both numerical and symbolic solving of differential equations (ODEs, PDEs, DAEs, DDEs,). With equations conveniently specified symbolically, the Wolfram Language uses both its rich set of special So the problem you're running into is that Mathematica's just not able to solve the differential equations exactly given the constraints you've offered. Let's first see if we can indeed meet your book's approximation, which does hold x is in a steady state; it's derivative is zero. x[t]=x[0]=xstar. An equation of particular interest in applied mathematics is the second order linear differential equation with nonconstant coefficients, x (1-x)y”+ [c- (a+b+1)x]y’-aby=0, where a, b, and c are constants.
In a system of ordinary differential equations there can be any number of unknown functions x
Preface to Mathematica Help The purpose of this supplement to Differential Equations with Linear Algebra is to provide some basic support in the use of Mathematica, analogous to the subsections of the text itself that offer similar
There are essentially two general paths to understanding and studying differential equations with Mathematica. Figure3shows these two paths. The first approach is more hands on, using DSolve and NDSolve to solve a differential equation and then using interactive elements of Mathematica to obtain a dynamic representation of the solution. No matter what you think about differential equations, you just got to have that book. The software that comes with it, is dynamite, and fully adds to Mathematica's Dsolve. Fact is, after you read the book you may understand what Ordinary Differential Equations are all about. "By the way there is nothing ordinary about Differential equations".

Mathematica is a great computer algebra system to use, especially if you are in applied areas where it is necessary to solve differential equations and other complicated problems. It was created by a brilliant entrepreneur, who was inspired by Maxima , the first computer algebra system in the world, and produced an elegant, coherent, and extremely general approach to computing.

Mathematica use is interactive, avoiding programming and user-created multi-step commands. Occasionally the text introduces "black-box" Mathematica commands which solve differential equations directly, but this typically just mentions such commands exist and checks or compares the solutions to the lengthier step-by-step computation.

However, if the matrix A was a function of x, then analytic solutions become hard, but the numerical code stays the same.
