Examples

Each section is followed by instructions for keystroke

examples that demonstrate the TI-36X Pro functions.

Examples assume all default settings, as shown in the Modes

section.

Some screen elements may differ from those shown in this

document.

Switching the calculator on and off

&turns on the calculator. % ' turns it off. The display

is cleared, but the history, settings, and memory are retained.

The APD™ (Automatic Power Down™) feature turns off the

calculator automatically if no key is pressed for about 5

minutes. Press &after APD. The display, pending

operations, settings, and memory are retained.

Display contrast

The brightness and contrast of the display can depend on

room lighting, battery freshness, and viewing angle.

To adjust the contrast:

1. Press and release the %key.

2. Press T(to darken the screen) or U(to lighten the

screen).

Home screen

On the Home screen, you can enter mathematical

expressions and functions, along with other instructions. The

answers are displayed on the Home screen. The TI-36X Pro

screen can display a maximum of four lines with a maximum

of 16 characters per line. For entries and expressions of more

than 16 characters, you can scroll left and right (!and ") to

view the entire entry or expression.

In the MathPrint™ mode, you can enter up to four levels of

consecutive nested functions and expressions, which include

fractions, square roots, exponents with ^, Ü, ex, and 10x.

When you calculate an entry on the Home screen, depending

upon space, the answer is displayed either directly to the right

of the entry or on the right side of the next line.

Special indicators and cursors may display on the screen to

provide additional information concerning functions or results.

Indicator Definition

2ND 2nd function.

FIX Fixed-decimal setting. (See Mode

section.)

SCI, ENG Scientific or engineering notation.

(See Mode section.)

DEG, RAD,

GRAD

Angle mode (degrees, radians, or

gradians). (See Mode section.)

L1, L2, L3 Displays above the lists in data

editor.

H, B, O Indicates HEX, BIN, or OCT

number-base mode. No indicator

displayed for default DEC mode.

The calculator is performing an

operation.

5 6 An entry is stored in memory before

and/or after the active screen. Press

#and $to scroll.

³´ An entry or menu displays beyond

16 digits. Press !or "to scroll.

Normal cursor. Shows where the

next item you type will appear.

Entry-limit cursor. No additional

characters can be entered.

Placeholder box for empty

MathPrint™ element. Use arrow

keys to move into the box.

2nd functions

Most keys can perform more than one function. The primary

function is indicated on the key and the secondary function is

displayed above it. Press %to activate the secondary

function of a given key. Notice that 2ND appears as an

indicator on the screen. To cancel it before entering data,

press % again. For example, %b25 < calculates

the square root of 25 and returns the result, 5.

Modes

Use qto choose modes. Press $ # ! " to choose a

mode, and < to select it. Press - or %s to

return to the Home screen and perform your work using the

chosen mode settings.

Default settings are highlighted in these sample screens.

DEG RAD GRAD Sets the angle mode to degrees,

radians, or gradians.

NORM SCI ENG Sets the numeric notation mode.

Numeric notation modes affect only the display of results, and

not the accuracy of the values stored in the unit, which remain

maximal.

NORM displays results with digits to the left and right of the

decimal, as in 123456.78.

MathPrint™ cursor. Continue

entering the current MathPrint™

element, or press an arrow key to

exit the element.

Indicator Definition

SCI expresses numbers with one digit to the left of the

decimal and the appropriate power of 10, as in

1.2345678E5 (which is the same as 1.2345678×105).

ENG displays results as a number from 1 to 999 times 10

to an integer power. The integer power is always a multiple

of 3.

Note: Eis a shortcut key to enter a number in scientific

notation format. The result displays in the numeric notation

format selected in the mode menu.

FLOAT 0 1 2 3 4 5 6 7 8 9 Sets the decimal notation mode.

FLOAT (floating decimal point) displays up to 10 digits,

plus the sign and decimal.

0 1 2 3 4 5 6 7 8 9 (fixed decimal point) specifies the

number of digits (0 through 9) to display to the right of the

decimal.

REAL a+bi r±q Sets the format of complex number

results.

REAL real results

a+bi rectangular results

r±q polar results

DEC HEX BIN OCT Sets the number base used for

calculations.

DEC decimal

HEX hexadecimal (To enter hex digits A through F, use

%§, %¨, and so on.)

BIN binary

OCT octal

CLASSIC MATHPRINT

CLASSIC mode displays inputs and outputs in a single

line.

MATHPRINT mode displays most inputs and outputs in

textbook format.

Multi-tap keys

A multi-tap key is one that cycles through multiple functions

when you press it.

For example, the Xkey contains the trigonometry functions

sin and sin/as well as the hyperbolic functions sinh and

sinh/. Press the key repeatedly to display the function that

you want to enter.

Multi-tap keys include z, X, Y, Z, C, D,

H, and g. Applicable sections of this guidebook describe

how to use the keys.

Menus

Menus give you access to a large number of calculator

functions. Some menu keys, such as %h, display a

single menu. Others, such as d, display multiple menus.

Press "and $ to scroll and select a menu item, or press

the corresponding number next to the item. To return to the

previous screen without selecting the item, press -. To

exit a menu and return to the Home screen, press %s.

%h(key with a single menu):

RECALL VAR (with values set to default of 0)

1: x = 0

2: y = 0

3: z = 0

4: t = 0

5: a = 0

6: b = 0

7: c = 0

8: d = 0

d(key with multiple menus):

Scrolling expressions and history

!" # $

Press ! or "to move the cursor within an expression that

you are entering or editing. Press %!or % " to move

the cursor directly to the beginning or end of the expression.

After you evaluate an expression, the expression and its

result are added automatically to the history. Use #and $

to scroll through the history. You can reuse a previous entry

by pressing <to paste it on the bottom line, where you

can edit it and evaluate a new expression.

Answer toggle

Press the r key to toggle the display result (when

possible) between fraction and decimal answers, exact

square root and decimal, and exact pi and decimal.

Pressing rdisplays the last result in the full precision of its

stored value, which may not match the rounded value.

Example

Last answer

The last entry performed on the home screen is stored to the

variable ans. This variable is retained in memory, even after

the calculator is turned off. To recall the value of ans:

•Press%i(ans displays on the screen), or

• Press any operations key (T, U, and so forth) as the first

part of an entry. ans and the operator are both displayed.
