Operation Manual

Chapter 1: Getting Started with the TI-84 Plus C Silver Edition 15
FULL, HORIZONTAL, GRAPH-TABLE
Full screen mode uses the entire screen to display a graph or edit screen.
Each split-screen mode displays two screens simultaneously.
Horiz (horizontal) mode displays the current graph on the top half of the screen; it displays the
home screen or an editor on the bottom half (Chapter 9 in the guidebook).
G-T (graph-table) mode displays the current graph on the left half of the screen; it displays the
table screen on the right half (Chapter 9 in the guidebook).
FRACTION TYPE: n/d, Un/d
n/d displays results as a simple fraction. Fractions may contain a maximum of six digits in the
numerator; the value of the denominator may not exceed 9999.
Un/d displays results as a mixed number, if applicable.
U, n, and d must be all be integers. If U is a non-
integer, the result may be converted
U n/d. If n or d is a non-integer, a syntax error is displayed. The
whole number, numerator, and denominator may each contain a maximum of three digits.
Note: To perform division with a complex number in the numerator or denominator, use regular
division instead of the n/d template.
ANSWERS: AUTO, DEC, FRAC-APPROX
Auto displays answers in a similar format as the input. For example, if a fraction is entered in an
expression, the answer will be in fraction form, if possible. If a decimal appears in the expression, the
output will be a decimal number.
Dec displays answers as integers or decimal numbers.
Frac-Approx attempts a fraction conversion using the number of decimals carried by the graphing
calculator. A fraction answer may be exact or approximate for any real number result.
Note: The Answers mode setting also affects how values in sequences, lists, and tables are displayed.
Choose
Dec or Frac to ensure that values are displayed in either decimal or fraction form. You can also
convert values from decimal to fraction or fraction to decimal using the FRAC shortcut menu or the
MATH menu.
GOTO 2ND FORMAT GRAPH: NO, YES
No does not display the FORMAT graph screen, but can always be accessed by pressing y..
Yes leaves the mode screen and displays the FORMAT graph screen when you press Í so that you
can change the graph format settings. To return to the mode screen, press z.
STAT DIAGNOSTICS: OFF, ON
Off displays a statistical regression calculation without the correlation coefficient (r) or the coefficient
of determination (r
2
).
On displays a statistical regression calculation with the correlation coefficient (r), and the coefficient of
determination (r
2
), as appropriate.
STAT WIZARDS: ON OFF
On: Selection of menu items in MATH PROB, STAT CALC, DISTR DISTR, DISTR DRAW and seq( in LIST OPS
displays a screen which provides syntax help (wizard) for the entry of required and optional arguments
into the command or function. The function or command will paste the entered arguments to the
Home Screen history or to most other locations where the cursor is available for input. Some
calculations will compute directly from the wizard. If a command or function is accessed from N
the command or function will paste without wizard support. Use Catalog Help for more syntax help
when needed. To use Catalog Help, select a menu item and then press Ã.
Off: The function or command will paste to the cursor location with no syntax help (wizard)
