Hi, I hope to help you. 1) In Mathematica, Abs[x] is left unevaluated if x is NOT a numeric quantity; so Integrate[Abs[x],x] returns the original input. 2) I began to study Mathematica with a very good book. Its last edition is entitled: "The Beginner's Guide to Mathematica Version 4", Jerry Glynn & Theodore Gray, by Cambridge University Press. A new book is also good: "The Student's Introduction to Mathematica", Bruce F. Torrence & Eve A. Torrence, by Cambridge University Press. However, you can visit the Mathematica Bookstore on the web at <www.wolfram.com/guide/bookstore>.
