Chapter 3: Q10E (page 131)

In Exercises10through 20 , use paper and pencil to identify the redundant vectors. Thus determine whether the given vectors are linearly independent.
10. $[\begin{matrix} 7 \\ 11 \end{matrix}] [\begin{matrix} 0 \\ 0 \end{matrix}]$ .

Short Answer

Expert verified

The vectors $[\begin{matrix} 7 \\ 11 \end{matrix}], [\begin{matrix} 0 \\ 0 \end{matrix}]$ are redundant and linearly dependent.

Step by step solution

Consider the set.

The vectors ${\overset{鈫�}{v}}_{1}, {\overset{鈫�}{v}}_{2}, . . ., {\overset{鈫�}{v}}_{m}$ in ${鈩�}^{n}$ are linearly dependent if and only if there are nontrivial relation among them.

If linearly dependent, then, the vectors are said to be redundant.

Consider the vectors, $[\begin{matrix} 7 \\ 11 \end{matrix}], [\begin{matrix} 0 \\ 0 \end{matrix}]$

Check for linear independency of vectors.

The reduced form of the matrix is,

$(\begin{matrix} 7 & 0 \\ 11 & 0 \end{matrix}) = (\begin{matrix} 7 & 0 \\ 0 & 0 \end{matrix}) = (\begin{matrix} 1 & 0 \\ 0 & 0 \end{matrix})$

Solve the above equations.

$V_{1} = [\begin{matrix} 1 \\ 0 \end{matrix}], v_{2} = [\begin{matrix} 0 \\ 0 \end{matrix}] v_{2} = 0 脳 v_{1}$

Final answer.

The vectors $[\begin{matrix} 7 \\ 11 \end{matrix}], [\begin{matrix} 0 \\ 0 \end{matrix}]$ are redundant and linearly dependent.
