例および操作のヒント

Use General Simplification Functions

Simplification of mathematical expression is not a clearly defined subject. There is no universal idea as to which form of an expression is simplest. The form of a mathematical expression that is simplest for one problem turns out to be complicated or even unsuitable for another problem. For example, the following two mathematical expressions present the same polynomial in different forms:

Choose Simplification Functions

Most mathematical expressions can be represented in different, but mathematically equivalent forms. Some of these forms might look simpler, for example, they can be visibly shorter. However, you might prefer other forms of the same expression for numeric computations. There is no general rule as to which form of an expression is the simplest. When solving a particular problem, you can choose the simplest form of an expression for this problem.

Convert Expressions Involving Special Functions

MuPAD provides many special functions commonly used in engineering and science. MuPAD uses standard mathematical notations for special functions. If you do not recognize a notation, see Mathematical Notations Used in Typeset Mode.

If You Want to Simplify Results Further

When simplifying a complicated expression, MuPAD can return results that would benefit from further simplifications. Suppose you want to simplify the following expression:
