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).
