Keys
1. I displays the following menu that lets
you change the
angle
RAD, and GRD without affecting the value
in the display.
DEG Sets degree mode.
RAD Sets radian mode.
GRD Sets gradient mode.
When you turn on the TI30X ÖS, it is
always in the DEG mode.

2. = displays a menu that lets you specify
the unit of an angle.
º Specifies degrees.
r Specifies radians.
g Specifies gradients.
DMS Specifies degrees (º), minutes
(´), and seconds (´´). It also lets
you convert an angle from
decimal degrees to DMS
notation.
Notes
The examples on the transparency masters
assume all default settings.
Angles with a trig function ignore the angle
mode setting and display results in the
original unit. Otherwise, angles (without a
trig function) are converted and displayed
according to the angle mode setting.
You enter decimal-degree angles the same
as you would any other number.
For decimal/DMS conversions, the
calculator interprets all values as degrees,
regardless of the angle-unit setting.
DMS angles are entered as º (degrees),
´ (minutes), and ´´ (seconds).
