Edition

Documentation Conventions

This Getting Started guide is similar to Chapter 1 of the TI-84 Plus C Silver

Edition guidebook. Several of the chapters in the full guidebook are

referenced in this Getting Started guide. The full guidebook is available

as a free download from education.ti.com/go/download.

In this document, the TI-84 Plus CSilver Edition graphing calculator is also

referred to as the TI-84 Plus C.

Using the TI-84 Plus C in the Classroom

The TI-84 Plus C shares many features with the TI-84 Plus. However, some

features you may be accustomed to using in the classroom may differ.

Some of these differences are listed here.

• TI-Navigator™ software supports the TI-84, TI-84 Plus, and TI-84 Plus

SE. TI-Navigator™ software does not support the TI-84 Plus C.

• TI-84 Plus C does not work with TI-Presenter™ video adapter or

ViewScreen™ overhead panel, but the TI-84 Plus C view option in the

TI-SmartView™ software allows you to project the graphing

calculator emulator to the classroom.

• Some files and variables are compatible between the TI-84 Plus C and

the TI-84 Plus family of graphing calculators. For more information

on file compatibility, see Linking Compatibility later in this chapter.

• The TI-84 Plus C graphing calculator comes equipped with a Li-ion

rechargeable battery. To ensure battery life, store the graphing

calculators in the TI-84 Plus C Charging Station, or connect individual

graphing calculators to a wall charger.

Warning: RAM memory will be lost if the battery charge is lost. You

should back up or archive your variables if your battery power gets

low.

For more information on the batteries and the charging station, see

Battery Information and TI-84 Plus C Charging Station later in this

chapter.

Using Color on the TI-84 Plus C

The TI-84 Plus C graphing calculator has many color options and a high

resolution display that allows more information to be shown on the

screen. The TI-84 Plus C uses color in the following ways:

2 Getting Started with the TI-84 Plus C Silver Edition

• Y= editor for line color.

• DRAW commands for line color, such as vertical lines, circles, and text

on the graph screen.

• The graph format screen for grid, axes, or border color, and applying

a background image or color.

• Statistical Plots.

The color options are selected using a spinner, which can contain various

options depending on the feature. Press |and ~to scroll through the

color options to set a color.

TI-84 Plus C Keyboard

Generally, the keyboard is divided into these zones: graphing keys,

editing keys, advanced function keys, and scientific calculator keys.

Keyboard Zones

Graphing—Graphing keys access the interactive graphing features. The

third function of these keys (t ^-a) displays the shortcut menus,

which include templates for fractions, n/d, quick matrix entry, and some

of the functions found on the MATH and VARS menus. When some

features are active, you may also see a shortcut menu in the tb

location for special shortcuts available in that particular feature.

Editing—Editing keys allow you to edit expressions and values.

Advanced—Advanced function keys display menus that access the

advanced functions.

Scientific—Scientific calculator keys access the capabilities of a standard

scientific calculator.

10. Press rto see the graph

and trace points.

Note: You can manipulate the

graph to “fit” an object in the

Background Image Var. You can

also use QuickPlot and Fit

Equation to fit an equation to a

shape. (See QuickPlot later in

this chapter.)

Using the Color.Coded Keyboard

The keys on the TI-84 Plus C are color-coded to help you easily locate the

key you need.

The light colored keys are the number keys. The keys along the right side of

the keyboard are the common math functions. The keys across the top set

up and display graphs. The Œkey provides access to applications such as

Polynomial Root Finder and Simultaneous Equation Solver, Inequality

Graphing, and more.

Note: Catalog Help is an application on the TI-84 Plus, but is built into

the TI-84 Plus C operating system. The Catalog Help contains syntax

information for most menu items, and most of the functions in the

catalog. To use Catalog Help on the TI-Plus C, select a menu item and

then press Ã.

The primary function of each key is printed on the keys. For example,

when you press , the MATH menu is displayed.

Using the yand ƒKeys

The secondary function of each key is printed above the key in the same

color as the ykey. When you press the ykey, the character,

abbreviation, or word printed above the other keys becomes active for

the next keystroke. For example, when you press yand then , the

TEST menu is displayed. This guidebook describes this keystroke

combination as y :.

The flashing cursor changes to Þwhen you press y. The Þ may show in

the cursor location, or in the status bar on the top of the screen.

Many keys also have a third function. These functions are printed above

the keys in the same color as the ƒkey. The third functions enter

alphabetic characters and special symbols, as well as access SOLVE and

shortcut menus. For example, when you press ƒand then , the

letter Ais entered. This guidebook describes this keystroke combination

as ƒ[A].

If you want to enter several alphabetic characters in a row, you can press

y 7 to lock the alpha key in the On position and avoid having to

press ƒmultiple times. Press ƒa second time to unlock it.

The flashing cursor changes to Øwhen you press ƒ, even if you are

accessing a function or a menu. The Ømay show in the cursor location, or

in the status bar on the top of the screen.
