Determining if a set of vectors is linearly independent

207 Views Asked by At

Assume that $v$ and $w$ are linearly independent vectors in $\Bbb R^3$. Determine which of the following sets of vectors is linearly independent.

a) $\left\{v\times w,0,v\right\}$

b) $\left\{v,v\times w,v\times \left(v\times w\right)\right\}$

c) $\left\{v,v+w,v+2w\right\}$

d) $\left\{v+w,v-w\right\}$

e) $\left\{v\times w,2v,\:w\times v\right\}$

f) $\left\{v\times w,\begin{pmatrix}1\\ 2\\ 3\end{pmatrix},v,w\right\}$

I am not entirely sure how to approach this problem. My intuition is telling me that $a$ is dependent because of the zero vector, $c$ is dependent because one row is a multiple of a another row, and I thought $f$ was dependent because $v$ and $w$ are vectors in $\Bbb R^3$ whereas that set has $4$ vectors.

But I know that I am supposed to find whether or not there is a non-trivial linear combination of vectors that equals zero. But I am not sure how to do that in this case as no numbers are have been provided.

Any help would be highly appreciated!

Note that

a) is not since it contains $\vec 0$

b) $\vec v \times (\vec v \times \vec w)=\vec 0$

c) $\vec u_2-\vec u_1=\vec v+\vec w-\vec v=\vec w$ and $\vec u_3-\vec u_2=\vec w$

d) prove that $a\vec u_1+b\vec u_2=0 \iff a=b=0$

e) $\vec v \times \vec w=-\vec w \times \vec v$

f) #vectors > dimension
