¦ Select a unit modifier (Ä Å Æ) for any part of an entry.
Entries with unit modifiers are interpreted accordingly,
overriding the Angle mode.
To convert an entry:
¦ Set the Angle mode to the unit you want to convert to.
Then use a unit modifier to designate the unit to convert
from. (Angles of trigonometric functions convert values
inside parentheses first.), or
¦ Select 4DMS, which converts an entry to DMS (Ä Å Æ)

Trigonometry
%Z[\

-1
Enter trigonometric functions (sin, cos, tan, sin
, cos
, tan
),
just as you would write them. Set the desired Angle mode
before starting trigonometric calculations.
%Y
Hyperbolics
% Y displays the
indicator and accesses the
HYP
hyperbolic function of the next trigonometry key that you
press. Angle modes do not affect hyperbolic calculations.
A B %]^
Logarithms
A yields the common logarithm of a number.
B yields the logarithm of a number to the base e
(e=2.819291929).
%] raises 10 to the power you specify.
%^ raises e to the power you specify.
%k
RectangularÍPolar
% k displays a menu to convert rectangular
coordinates (x,y) to polar coordinates (r,q) or vice versa.
Set Angle mode, as necessary, before starting calculations.
%l
Constants
% l turns Constant mode on and lets you define a
constant.
To store an operation to K and recall it:
1. Press %l.
2. Enter any combination of numbers, operators, and/or
values, up to 44 characters, beginning with an operator.
3. Press < to save the operation. K displays in the
indicator line.
4. Each subsequent time you press <, the TI-30X Ö
recalls the stored operation and applies it to the last
answer or the current entry.
Press % l again to turn Constant mode off.

Memory
The TI-30X Ö has 5 memory variables—

You can store a real number or an expression that results
in a real number to a memory variable.
¦ z accesses the menu of variables.
¦ L lets you store values to variables.
¦ % h recalls the values of variables.
¦ % { clears all variable values.
%‚ %d %C
Notation
% ‚ displays the Decimal Notation mode menu.
These modes affect only the display of results.
(default)
F
restores standard notation (floating-decimal) format.
sets decimal places to n (0–9), retaining
0123456789
numeric notation mode format.
% d displays the Numeric Notation mode menu.
These modes affect only the display of results.
¦ FLO (default): Floating Notation, with digits to the left and
right of the decimal
¦ SCI: Scientific Notation
¦ ENG: Engineering Notation (exponent is a multiple of 3)
% C enters a value in Scientific Notation, regardless
of the numeric notation mode. Press M before entering a
negative exponent.
