Introduction
The HP-15C provides several advanced capabilities never before combined so conveniently
in a handheld calculator:

Finding the roots of equations.

Evaluating definite integrals.

Calculating with complex numbers.

Calculating with matrices.
The HP-15C Owner's Handbook gives the basic information about performing these
advanced operations. It also includes numerous examples that show how to use these
features. The owner's handbook is your primary reference for information about the advanced
functions.
This HP-15C Advanced Functions Handbook continues where the owner's handbook leaves
off. In this handbook you will find information about how the HP-15C performs the
advanced computations and information that explains how to interpret the results that you
get.
This handbook also contains numerous programs, or applications. These programs serve two
purposes. First, they suggest ways of using the advanced functions, so that you might use
these capabilities more effectively in your own applications. Second, the programs cover a
wide range of applications—they may be useful to you in the form presented in this
handbook.
Note: The discussions of most topics in this handbook presume that you
already understand the basic information about using the advanced functions
and that you are generally familiar with the subject matter being discussed.
