Are the vectors v1 = (1 , 2, 3), v2 = (2, 4, 6), and v3 = (1, 1, 3) linearly independent or dependent? Since v2 is a scalar multiple of v1, both v1 and v2 are linearly dependent, but what does that say about the linear dependence of the three vectors as a whole?

Solutions

Expert Solution

Concept : If one vector can be expressed a linear combination of another vectors , then those vectors can be said as Linearly dependent.

If v2 can be expressed as linear combination of v1 and v3 such that,

v2 = a1V1 + a2V2 where at least one of the scalar a1, a2 is non zero

Here,

v2 = 2v1 + 0v3 . Thus , all three vectors are Linearly dependent.
