4DMS MATH/Angle menu
expression 4DMS
list 4DMS
matrix 4DMS
Interprets the argument as an angle and displays
the equivalent
DMS ( DDDDDD ¡ MM ¢ SS.ss £) number.
See ¡, ', " on page 905 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:
45.371 4DMS ¸ 45ó 22'15.6"
{45.371,60} 4DMS ¸
{45ó 22'15.6" 60ó }

⇒ expression
Returns the “dot” product of two lists.
dotP({a,b,c},{d,e,f}) ¸
aø d + bø e + cø f
dotP({1,2},{5,6}) ¸ 17
dotP( vector1 , vector2 ) ⇒
⇒⇒
⇒ expression
Returns the “dot” product of two vectors.
Both must be row vectors, or both must be
column vectors.
dotP([a,b,c],[d,e,f]) ¸
aø d + bø e + cø f
dotP([1,2,3],[4,5,6]) ¸ 32
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 1.25xù cos(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.
Note: Regraphing erases all drawn items.
In function graphing mode and
ZoomStd
window:
DrawInv 1.25xù cos(x) ¸
