4DMS
Interprets the argument as an angle and displays
the equivalent
DMS (
DDDDDD
¡
MM
¢
SS.ss
£
) number.
See
¡
, ', " on page 883 for DMS (degree, minutes,
seconds) format.
Note:
4DMS
will convert from radians to degrees
when used in radian mode. If the input is followed
by a degree symbol (
¡
), no conversion will occur.
You can use
4DMS
only at the end of an entry line.
In Degree angle mode:

by plotting
x
values
on the y axis and
y
values on the x axis.
x
is the independent variable.
Note: Regraphing erases all drawn items.
