In Exercises 15 and 16, list five vectors in Span{𝐯1, 𝐯2} ....

In Exercises 15 and $16,$ list five vectors in $\operatorname{Span}\left\{\mathbf{v}_{1}, \mathbf{v}_{2}\right\} .$ For each vector, show the weights on $\mathbf{v}_{1}$ and $\mathbf{v}_{2}$ used to generate the vector and list the three entries of the vector. Do not make a sketch. $$ \mathbf{v}_{1}=\left[\begin{array}{r}{7} \\ {1} \\ {-6}\end{array}\right], \mathbf{v}_{2}=\left[\begin{array}{r}{-5} \\ {3} \\ {0}\end{array}\right] $$

Key Concepts

Vector Representation

Vector representation in this context refers to expressing vectors as an ordered list of components that result from the linear combination of given basis vectors. This formal representation makes it clear how the weights affect each entry of the resulting vector.

Subspace

A subspace is a set of vectors that is closed under vector addition and scalar multiplication. The span of a set of vectors is always a subspace because any linear combination of the vectors remains within that collection, satisfying the properties of a vector space.

Linear Combination

A linear combination involves multiplying each vector by a scalar (weight) and then adding the results together. This process shows how different vectors can be generated by scaling and summing the basic vectors, and it forms the foundation for constructing the span.

Span

The span of a set of vectors is the collection of all possible vectors that can be formed by taking linear combinations of those vectors. It represents a subspace of the vector space and defines all the directions and magnitudes you can reach using the given vectors with various scalars.

Scalar Multiplication

Scalar multiplication is the process of scaling a vector by a given number (the weight). Multiplying a vector by a scalar changes its magnitude and possibly its direction if the scalar is negative, and is an essential operation in forming linear combinations.
