Sometimes Scientific Notebook returns answers that are not in the form you need. You can take advantage of items such as Simplify, Combine, Expand, and Factor under the Maple menu to rewrite these answers. Here is an example that illustrates their use.
The integral
2xcos bxdx looks just as straightforward but
requires several extra steps to get the answer into an equivalent final
form. (See the exercisesDM7-9.tex#Exercises at the end of
this chapter.) Simplification of algebraic expressions is more subtle than
it might at first appear. Sometimes you just have to experiment with the
menu items Simplify, Combine, Expand, and Factor to get expressions into a manageable form. This interaction with the
system is a natural part of the machine-human interface.
