Special Features of the TI-84 Plus C
3.5 Megabytes of Available Memory
3.5 MB of available memory is built into the TI-84 Plus C Silver Edition. About 21 kilobytes (K) of RAM
(random access memory) are available for you to compute and store functions, programs, and data.
About 3.5 M of user data archive allow you to store data, programs, applications, or any other variables
to a safe location where they cannot be edited or deleted inadvertently. You can also free up RAM by
archiving variables to user data. For details, refer to Chapter 18 in the guidebook.
Applications
Some applications are preloaded on your TI-84 Plus C, and others can be installed to customize the
TI-84 Plus C to your needs. You can install applications and the TI Connect™ software at
education.ti.com/go/download.
The 3.5 MB archive space lets you store up to 216 applications at one time on the TI-84 Plus C.
Applications can also be stored on a computer for later use or linked unit-to-unit. For details, refer to
Chapter 18 in the guidebook.
Archiving
You can store variables in the TI-84 Plus C user data archive, a protected area of memory separate from
RAM. The user data archive lets you:
• Store data, programs, applications or any other variables to a safe location where they cannot be
edited or deleted inadvertently.
• Create additional free RAM by archiving variables.
By archiving variables that do not need to be edited frequently, you can free up RAM for applications
that may require additional memory. For details, refer to: Chapter 18 in the guidebook.
Other TI-84 Plus C Features
Graphing
You can store, graph in color, and analyze up to 10 functions, up to six parametric functions, up to six
polar functions, and up to three sequences. You can use DRAW instructions to annotate graphs in color.
The graphing chapters appear in this order: Function, Parametric, Polar, Sequence, and DRAW. For
graphing details, refer to Chapters 3, 4, 5, 6, and 8 in the guidebook.
Sequences
You can generate sequences and graph them over time. Or, you can graph them as web plots or as
phase plots. For details, refer to Chapter 6 in the guidebook.
Tables
You can create function evaluation tables to analyze many functions simultaneously. For details, refer
to Chapter 7 in the guidebook.
Split Screen
You can split the screen horizontally to display both a graph and a related editor (such as the Y=
editor), the table, the stat list editor, or the home screen. Also, you can split the screen vertically to
display a graph and its table simultaneously. For details, refer to Chapter 9 in the guidebook.
