Vectors Zero vector and unit vectors A vector with magnitude 0 is called the zero vector, written 0. A vector with magnitude 1 is called a unit vector.

Vectors are equal if they have the same magnitude and the same direction.

a = b

Inverse Vectors The inverse of a vector is a vector of equal magnitude but in the opposite direction. The inverse of is - or and the inverse of a is -a.
