How can you tell if two vectors are collinear?

Answer 1

If one vector is a multiple of the other vector than they are collinear).

Let n equal any natural number (1, 2, 3, 4, ...) and vequal a vector with both amagnitudeand a direction.

vn = nv (e.g., v3 = 3v)

Vn will always be collinear to v, because it is just a multiple of v (the multiple being n)

To verify if two vectors are collinear, if you can factor out a multiple, to return to theoriginalvector, than they are collinear.
