This new addition to the ever growing library of Mathematica-related texts is a welcome one. The authors are well-known in the Mathematica community and have extensive experience with its uses at both undergraduate and graduate levels. The book is mostly about linear ordinary differential equations (ODE's), and includes brief accounts of systems of ODE's and one chapter on partial differential equations (PDE's). The book shows how Mathematica can be used to facilitate the symbolic manipulation of intermediate steps leading to the solution of a differential equation and illustrates the results using the graphics commands. This is followed by instruction in the use of Mathematica's built-in ODE solvers and explanations on how to attack a given problem by traditional methods and the help of Mathematica.
