Command line calculations
This section provides a number of examples of common types of
calculations. The keystrokes needed—in algebraic mode—to enter the
calculation on the command line, and the result in both exact and
approximate mode, are listed. (The examples assume that the calculator
is operating with its default mode settings.)
Chapters 5 and 6 explain how to use the conunands and functions of the
calculator’s computer algebra system to set up and solve more-complex
calculations. See chapter 5 for information on how to configure modes to
get symbolic results to calculations.
