Chapter 1: Getting Started with the TI-84 Plus C Silver Edition 13

MATHPRINT, CLASSIC

MathPrint™ mode displays most inputs and outputs the way they are shown in textbooks, such as

and .

Classic mode displays expressions and answers as if written on one line, such as 1/2 + 3/4.

Note: If you switch between these modes, most entries will be preserved; however matrix calculations

will not be preserved.

NORMAL, SCI, ENG

Notation modes only affect the way an answer is displayed on the home screen. Numeric answers can

be displayed with up to 10 digits and a two-digit exponent and as fractions. You can enter a number in

any format.

Normal notation mode is the usual way we express numbers, with digits to the left and right of the

decimal, as in

12345.67.

Sci (scientific) notation mode expresses numbers in two parts. The significant digits display with one

digit to the left of the decimal. The appropriate power of 10 displays to the right of å, as in

1.234567â4.

Eng (engineering) notation mode is similar to scientific notation. However, the number can have one,

two, or three digits before the decimal; and the power-of-10 exponent is a multiple of three, as in

12.34567â3.

Note: If you select

Normal notation, but the answer cannot display in 10 digits (or the absolute value is

less than .001), the TI-84 Plus C expresses the answer in scientific notation.

FLOAT, 0 1 2 3 4 5 6 7 8 9

Float (floating) decimal mode displays up to 10 digits, plus the sign and decimal.

FIX 0123456789 decimal mode specifies the number of digits (0 through 9) to display to the right of the

decimal for decimal answers.

The decimal setting applies to

Normal, Sci, and Eng notation modes.

The decimal setting applies to these numbers, with respect to the Answer mode setting:

• An answer displayed on the home screen

• Coordinates on a graph (Chapters 3, 4, 5, and 6 in the guidebook)

•The

Tange nt ( DRAW instruction equation of the line, x, and dy/dx values (Chapter 8 in the

guidebook)

• Results of CALCULATE operations (Chapters 3, 4, 5, and 6 in the guidebook)

• The regression equation stored after the execution of a regression model (Chapter 12 in the

guidebook)

RADIAN, DEGREE

Angle modes control how the TI-84 Plus C 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.

FUNCTION, PARAMETRIC, POLAR, SEQ

Graphing modes define the graphing parameters. Chapters 3, 4, 5, and 6 in the guidebook describe

these modes in detail.

Func (function) graphing mode plots functions, where Y is a function of X (Chapter 3).
