Preface

You have in your hands a compact symbolic and numerical computer that will facilitate calculation and mathematical analysis of problems in a variety of disciplines, from elementary mathematics to advanced engineering and science subjects.

The present Guide contains examples that illustrate the use of the basic calculator functions and operations. The chapters in this user's manual are organized by subject in order of difficulty: from the setting of calculator modes, to real and complex number calculations, operations with lists, vectors, and matrices, graphics, calculus applications, vector analysis, differential equations, probability and statistics.

For symbolic operations the calculator includes a powerful Computer Algebraic System (CAS), which lets you select different modes of operation, e.g., complex numbers vs. real numbers, or exact (symbolic) vs. approximate (numerical) mode. The display can be adjusted to provide textbook-type expressions, which can be useful when working with matrices, vectors, fractions, summations, derivatives, and integrals. The high-speed graphics of the calculator are very convenient for producing complex figures in very little time.

Thanks to the infrared port and the RS232 cable available with your calculator, you can connect your calculator with other calculators or computers. The high-speed connection through infrared or RS232 allows the fast and efficient exchange of programs and data with other calculators or computers.

We hope your calculator will become a faithful companion for your school and professional applications. This calculator is, without any doubt, the top of the line for hand-held calculating devices.
