Maple does not expand the result. Notice that the result does not look like the expressions previously entered. Maple will not always be able to return an expression to its previous form. Because any letter used in a Maple session is considered a variable, you must specify with respect to what variable differentiation and integration should occur. The result is not exactly like the integrand, but it is in a form similar enough to recognize that they are the same expression.
Simplification is a difficult problem.
Generally, the last term of the series will be the order term, where the order is decided by a global Maple variable which can be defined by the user. Permission to use this document is granted so long as the author is acknowledged and notified. Copyright 1995-1999, Indiana University .
