Question

Define antiparallel vectors.​

Answer 1

Answer:

Antiparallel vectors

In a Euclidean space, two directed line segments, often called vectors in applied mathematics, are antiparallel, if they are supported by parallel lines and have opposite directions. In that case, one of the associated Euclidean vectors is the product of the other by a negative number.

Answer 2

Two vectors are said to be antiparallel, if they point in exactly opposite direction. The magnitudes of the two vectors NEED NOT BE THE SAME. What is important are the directions of the two vectors. If (l,m,n) are the direction cosines of a vector, its antiparallel vector will have its direction cosines as ( -l,-m,-n)
