2.2 Vectors

Vectors are stored using their Cartesian coordinates.

Vector operators

u + v

Sum of u and v.

u - v

Difference of u and v.

k * u

Scalar product of u by k.

u / k

Scalar quotient of u by k.

u * v

Dot product of u and v.

Vector related functions

vector(x, y)

Vector of Cartesian coordinates (x, y).

vector(r, a)

Vector of polar coordinates (r, a).

vector(A, B)

Vector going from point A to point B.

abscissa(u)

Abscissa of u.

ordinate(u)

Ordinate of u.

length(u)

Length of u.

arg(u)

Polar angle of u (in degrees).

angle(u, v)

Angle between u and v (in degrees).
