expression1
,
expression2
Displays the Graph screen and draws a line
tangent to
expression1
at the point specified.
expression1
is an expression or the name of a
function, where
x
is assumed to be the
independent variable, and
expression2
is the
x
value of the point that is tangent.
Note
: In the example shown,
expression1
is
graphed separately.
LineTan
does not graph
expression1.

Displays the Graph screen and draws, erases, or
inverts a vertical line at window position

.
If
drawMode
= 1, draws the line (default).
If
drawMode
= 0, turns off the line.
If
drawMode
=
ë
1, turns a line that is on to off or
off to on (inverts pixels along the line).
