4DMS
Interprets the argument as an angle and displays
the equivalent DMS (

SS.ss
£) number.
See ¡, ', " on page 910for DMS (degree, minutes,
seconds) format.
Note: 4

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 4

4DMS only at the end of
an entry line.
In Degree angle mode:

DrawFunc CATALOG
DrawFunc
expression
Draws
expression
as a function, using x as the
independent variable.
Note: Regraphing erases all drawn items.
In function graphing mode and ZoomStd
window:
DrawFunc 1.25xùcos(x) ¸
DrawInv CATALOG
DrawInv
expression
Draws the inverse of
expression
by plotting x
values on the y axis and y values on the x axis.
x is the independent variable.
