Texas Instruments TITANIUM TI-89 - Manual (Page 922)

Appendix B: Technical Reference 923
Note: If you select NORMAL, but the answer cannot be displayed in the number of digits
selected by Display Digits, the TI-89 Titanium / Voyage™ 200 displays the answer in
SCIENTIFIC notation. If Display Digits = FLOAT, scientific notation will be used for
exponents of 12 or more and exponents of -4 or less.
Complex Format Complex Format Complex Format Complex Format
Specifies whether complex results are displayed and, if so, their format.
Vector Format Vector Format Vector Format Vector Format
Determines how 2-element and 3-element vectors are displayed. You can enter vectors
in any of the coordinate systems.

Determines how results are displayed on the Home screen.
Note: For a complete description of these settings, refer to “Formats of Displayed
Results” in the Operating the Calculator module.
3:ENGINEERING
Similar to scientific notation. However:
• The number may have one, two, or three digits
before the decimal.
• The power-of-10 exponent is a multiple of three.
For example, 12.34567
E
3 means 12.34567
×
10 3
1:REAL
Does not display complex results. (If a result is
a complex number and the input does not
contain the complex unit i, an error message is
displayed.)
2:RECTANGULAR Displays complex numbers in the form: a+b
i
3:POLAR Displays complex numbers in the form: r e i q
1:RECTANGULAR
Coordinates are in terms of
x
,
y
, and
z
. For
example,
[3,5,2]
represents
x = 3
,
y = 5
, and
z = 2.
2:CYLINDRICAL Coordinates are in terms of r, q , and z. For
example, [3,
∠
45,2] represents r = 3, q = 45,
and z = 2.
3:SPHERICAL Coordinates are in terms of r, q , and f . For
example, [3,
∠
45,
∠
90] represents r = 3,
q = 45, and f = 90.
1:OFF
Results are displayed in a linear, one-
dimensional form.
For example, p ^2, p /2, or ‡ ((x-3)/x)
2:ON
Results are displayed in conventional
mathematical format.
For example, p
2, ,
or
