mutual positions of vectors
In this entry, we work within a Euclidean space .
Since both and are non-zero, . So is a binary relation on on and called the parallelism. If , then and are said to be in the same direction, and we denote this by ; if , then and are said to be in the opposite or contrary directions, and we denote this by .
Two Euclidean vectors and are perpendicular, denoted by , iff
The angle between two non-zero vectors and is obtained from
The angle is chosen so that .
