Dot Product Line

Drag B to two other points such that the dot product of the two vectors is always 5.

Once you have the general pattern for the points, write an equation that describes the position of these points using the CURVE[] command.

Does your graph pass the drag test?

Remember...
CURVE[expression for x, expression for y, parameter, start, end]

Repeat this for point C.
Repeat this for other dot product values.
What "dragging patterns" do you notice?
How is the slope of the points related to the stationary vector?
