When to Stay Away from the Book Mode

In some situations you should stay away from using a book
mode environment
when conversing with Maxima. This is the case always whenever Maxima
is likely to ask you further questions about a specific evaluation.
This will happen, for example, when you attempt to integrate a function,
and Maxima needs additional information about signs of various symbols.
I you have already forked a Maxima process to which your book mode
talks, you should be able to locate its corresponding Emacs buffer by
issuing the command

C-x b *maxima-eval*

Once in that buffer carry on the computation:

If you issued the `integrate` directive from within the book mode, Emacs
would end up hanging. The book mode, as you see, is a somewhat mixed blessing.
In plain mathematical notation, we have just produced the following result:

Maple doesn't ask this kind of questions for this integral. The result is also
grouped somewhat differently:

that is

Mathematica notation has its usual quirks here, and, moreover, Mathematica warns
you about a possible confusion with the Zeeman Beta function.
