We can decide if two vectors are perpendicular, parallel, or antiparallel by looking at the dot product between the vectors. These follow from ...
ELEMENTS OF VECTORSperpendicular to the plane requires a way to determine when two vectors are perpendicular. This can be done using the idea of the dot product of two vectors. 13 VectorsNotice 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 ...
