isolate variable x) and then let it loose. Designed to supplement most textbooks on ordinary differential equations (ODEs), this book has been updated for Mathematica 6. It focuses on the features of Mathematica that are useful for analyzing differential equations to deepen the reader's understanding. A comprehensive introduction to the applications of symmetry analysis to differential equations. These applications, emerged from discoveries by Sophus Lie, can be used to find exact solutions and to verify and develop numerical schemes. The book includes both theoretical considerations and practical applications of use to physicists, chemists, mathematicians and engineers. Partial Differential Equations Version 11 adds extensive support for symbolic solutions of boundary value problems related to classical and modern PDEs.

## In calculating a system of differential equations, I used 3 different methods: EigenSystem, DSolve and MatrixExp. DSolve and MatrixExp porduced the same answers but a different answers than EigenSystem and I don't understand why (See Attached). In all three cases, I used a default value of {1,1} for the values of the arbitrary constants.

A partial differential equation (PDE) is a relationship between an unknown function u(x_ 1,x_ 2,\[Ellipsis],x_n) and its derivatives with respect to the variables x_ 1,x_ 2,\[Ellipsis],x_n. PDEs occur naturally in applications; they model the rate of change of a physical quantity with respect to both space variables and time variables. system of equationsmatriceswolframalpha.com tutorial In a system of ordinary differential equations there can be any number of unknown functions u_i, but all of these functions must depend on a single "independent variable" t, which is the same for each function. Partial differential equations involve two or more independent variables.
