14 Getting Started
Getting Started has introduced you to basic calculator operation and the table
and function graphing features of the TI
-
80. The remainder of this Guidebook
describes these features in more detail and also covers other capabilities of the
TI
-
80.
You can enter fractions directly from the keyboard and
perform calculations with fractions. You can convert between
fractions and their decimal equivalents. In
MANSIMP
mode,
you can simplify fractions step-by-step. The TI
-
80 tells you
when a fraction can be simplified and shows the common
factor after simplification (Chapter 3).
You can store, graph, and analyze up to four functions
(Chapter 4) and up to three parametric functions (Chapter 5).
You can use Draw operations to annotate graphs (Chapter 7).
You can create function evaluation tables to analyze multiple
functions simultaneously (Chapter 6).
You can enter and save up to six lists for use in statistical
analysis. You also can use lists to evaluate expressions at
multiple values simultaneously (Chapter 8).
You can perform one-variable and two-variable list-based
statistical analysis, including regression analysis, and plot the
data as histograms, points, x-y lines, or box-and-whisker plots.
You can define and save three statistical plot definitions
(Chapter 9).
You can enter and save programs that include extensive
control and input/output instructions (Chapter 10)
