Selecting CAS settings
CAS stands for Computer Algebraic System. This is the mathematical core of
the calculator where the symbolic mathematical operations and functions are
programmed and performed. The CAS offers a number of settings can be
adjusted according to the type of operation of interest. These are:
• The default independent variable
• Numeric vs. symbolic mode
• Approximate vs. Exact mode
• Verbose vs. Non-verbose mode
• Step-by-step mode for operations
• Increasing power format for polynomials
• Rigorous mode
• Simplification of non-rational expressions
Details on the selection of CAS settings are presented in Appendix C.
