About the Examples in This Book
All the examples given in this book were generated by running an actual copy of the Mathematica TE Teacher's Edition, Version 1.0. If you have a copy of this version, you should be able to reproduce the examples on your computer as they appear in the book.
There are, however, a few points to watch:
Until you are familiar with Mathematica TE, make sure to type the input exactly as it appears in the book. Do not change any of the capital letters or brackets. Later, you will learn what things you can change. When you start out, however, it is important that you do not make any changes; otherwise you may not get the same results as in the book.
Never type the prompt In[n]:= that begins each input line. Mathematica TE will do that for you. Type only the text that follows this prompt.
You will see that the lines in each dialog are numbered in sequence. Most subsections in the book contain separate dialogs. To make sure you get exactly what the book says, you should start a new Mathematica TE session each time the book does.
Any examples that involve random numbers will generally give different results than in the book, since the sequence of random numbers produced by Mathematica TE is different in every session.
Some examples that use machine-precision arithmetic may come out differently on different computer systems. This is a result of differences in floating-point hardware. If you use arbitrary-precision Mathematica TE numbers, you should not see differences.
If the version of Mathematica TE is more recent than the one used to produce this book, then it is possible that some results you get may be different.
