DMS entry: '
MATH ANGLE menu
In a trig calculation, the
result of a DMS entry is
treated as degrees in the
Degree angle mode only. It
is treated as radians in
Radian angle mode.
degrees ' minutes ' seconds '
Designates the entered angle is in DMS format. degrees
(
 999,999), minutes (< 60), and seconds (< 60, may
have decimal places) must be entered as real numbers,
not as variable names or expressions.
Do not use ¡ and " symbols to specify degrees and
seconds . For example, 5 ¡59' is interpreted as implied
multiplication of 5 ¡ ¹ 59' according to the current angle
mode setting.
