Angle modes control how the TI
.
83 interprets angle values
in trigonometric functions and polar/rectangular
conversions.
Radian mode interprets angle values as radians. Answers
display in radians.
Degree mode interprets angle values as degrees. Answers
display in degrees.
Graphing modes define the graphing parameters. Chapters
3, 4, 5, and 6 describe these modes in detail.
Func (function) graphing mode plots functions, where Y is
a function of
X (Chapter 3).
Par (parametric) graphing mode plots relations, where X
and Y are functions of T (Chapter 4).
Pol (polar) graphing mode plots functions, where r is a
function of
q
(Chapter 5).
Seq (sequence) graphing mode plots sequences (Chapter 6).
Connected plotting mode draws a line connecting each
point calculated for the selected functions.
Dot plotting mode plots only the calculated points of the
selected functions.
