Vector Commands

CurvatureVector

CurvatureVector[Point, Function]: Yields the curvature vector of the function in the given point.

CurvatureVector[Point, Curve]: Yields the curvature vector of the curve in the given point.

Direction

Direction[Line]: Yields the direction vector of the line.        
Note: A line with equation ax + by = c has the direction vector (b, - a).

PerpendicularVector

PerpendicularVector[Line]: Returns the perpendicular vector of the line.          
Note: A line with equation ax + by = c has the perpendicular vector (a, b).

PerpendicularVector[Vector v]: Returns the perpendicular vector of the given vector.          
Note: A vector with coordinates (a, b) has the perpendicular vector (-b, a).

UnitPerpendicularVector

UnitPerpendicularVector[Line]: Returns the perpendicular vector with length 1 of the given line.

UnitPerpendicularVector[Vector]: Returns the perpendicular vector with length 1 of the given vector.

UnitVector

UnitVector[Line]: Yields the direction vector with length 1 of the given line.

UnitVector[Vector]: Yields a vector with length 1, which has the same direction and orientation as the given vector.

Vector

Vector[Point A, Point B]: Creates a vector from point A to point B.

Vector[Point]: Returns the position vector of the given point.
