Answer to Question #105887 in Analytic Geometry for Jflows

Question

If α times \eta=0 then \\Right (\alpha) and \eta are ____

a.like vectors

b.zero vectors

c.parallel

d.perpendicular

Answer 1

If a=kb then a, b are parallel vectors, if k is positive they are like vectors. If a=0 and b=0 as vectors, then a and b are zero vectors.

If a.b is zero then a and b are perpendicular.
