Locus Tool
Select a point B that depends on another point A and whose locus should be drawn. Then, select point A to create the locus of point B.
-
Type
f(x) = x^2 – 2 x – 1
into the Input Bar and press the Enter-key. -
Place a new point A on the x-axis (see
Point tool or Point command).
-
Create point
B = (x(A), f'(x(A)))
that depends on point A. -
Select the tool
Locus and successively select point B and point A.
-
Drag point A along the x-axis to see point B moving along its locus line.
Point A has to be a point on an object (e.g. line, segment/interval, circle). |

Locus is undefined, if the dependent point depends on Point Command with two parameters or PathParameter Command. |
