Points, Line Segments, and Vectors
Plots two points
P and
Q in space, with options to draw
the line segment between
P and
Q and the vector from
P to
Q (with tail at the origin).

How to use
Enter values for the coordinates
x_{1},
y_{1}, and
z_{1} (for the point P) and
x_{2},
y_{2}, and
z_{2} (for the point Q) into the
corresponding text input fields.
Example:
P=(1,-2,2), Q=(3,2,4)
To select what is drawn, click on the radio buttons:
- Points only: draw the points
P=(x_{1},y_{1},z_{1})
and
Q=(x_{2},y_{2},z_{2})
with rectangular boxes to indicate coordinates.
- Points and Line Segment: draw P and Q as above,
but also include the line segment between P and Q.
- Points, Line Segment, and Vector:
draw P and Q and the line segment between P and Q
as above, but also include the vector from P to Q, drawn
with its tail at the origin (0,0,0).
The
buttons under the graph allow various manipulations of
the graph coordinates.
The text input fields can accept
real numbers in decimal notation.
Examples
P=(1,-2,2), Q=(3,2,4)

Other Notes
The point P and its coordinate box are drawn
in blue.
The point Q and its coordinate box are drawn
in green.
The line segment between P and Q and the
vector from P to Q are drawn in
red.
