PerpendicularVector Command
- PerpendicularVector( <Line> )
-
Returns the perpendicular vector of the line.
Let Line((1, 4), (5, -3)) be the line j. PerpendicularVector(j) yields the perpendicular vector u=(7, 4)
of the line j.
|
A line with equation ax + by = c has the perpendicular vector (a, b). |
- PerpendicularVector( <Segment> )
-
Returns the perpendicular vector of the segment with the same length.
Let Segment((3, 2), (14, 5)) be the segment k. PerpendicularVector(k) yields the perpendicular vector
u=(-3, 11) of the segment k.
- PerpendicularVector( <Vector> )
-
Returns the perpendicular vector of the given vector.
Let Vector((-12, 8)) be the vector u. PerpendicularVector(u) yields the perpendicular vector v=(-8, -12)
of the vector u.

In the |
PerpendicularVector((a, b)) yields the vector \{-b, a}.
- PerpendicularVector( <Plane> )
-
Creates a vector orthogonal to the plane.
PerpendicularVector(xOyPlane) yields the perpendicular vector u=(0, 0, 1) of the xOy plane.
