13 Vectors
Notice that the dot product of two vectors is a number and not a vector. For 3 dimensional vectors, we define the dot product similarly: Dot Product in R. 3.
Points, Lines, Planes and Vectorsa) The vector [?2, 3] is perpendicular to [3, 2] (test this by taking the dot product of the two vectors) and hence is a direction vector for the line. The ... 4. Vector Geometry| Afficher les résultats avec : Lecture 1 .pdftd
