Radian, Degree
Angle settings control how the TI
.
82 interprets angle values in trig
functions and polar/rectangular conversions.
Radian
interprets the values as radians. Answers display in radians.
Degree
interprets the values as degrees. Answers display in degrees.
Func, Par, Pol, Seq
Func
(function) graphing plots functions where
Y
is a function of
X
(Chapter 3).
Par
(parametric) graphing plots relations where
X
and
Y
are functions of
T
(Chapter 4).
Pol
(polar) graphing plots functions where
R
is a function of
q
(Chapter 5).
Seq
(sequence) graphing plots sequences (Chapter 6).
Connected, Dot
Connected
draws a line between the points calculated for the selected
functions.
Dot
plots only the calculated points of the selected functions.
Sequential, Simul
Sequential
graphing evaluates and plots one function completely before the
next function is evaluated and plotted.
Simul
(simultaneous) graphing evaluates and plots all selected functions
for a single value of
X
and then evaluates and plots them for the next value
of
X
.
FullScreen, Split
FullScreen
uses the entire screen to display a graph or edit screen.
Split
screen displays the current graph on the upper portion of the screen
and the Home screen or an editor on the lower portion (Chapter 9).
