• Defining a Basis: A set of vectors that is linearly independent and spans the entire vector space.
• Linear Independence: Vectors are linearly independent if no vector in the set can be represented as a linear combination of the others.
• Spanning the Space: Every vector in the vector space can be expressed as a linear combination of the basis vectors.

Exploring ℝ³: The Three-Dimensional Space

In the realm of ℝ³, vectors represent points in a three-dimensional coordinate system. This space, characterized by its width, height, and depth, serves as a canvas for various mathematical operations and geometric interpretations.

Now, let’s evaluate a set of candidate vectors to determine if they form a basis for ℝ³. Consider the vectors:

${\mathbf{v}}_1=\left[\begin{array}{c}1\\ 0\\ 0\end{array}\right],{\mathbf{v}}_2=\left[\begin{array}{c}0\\ 1\\ 0\end{array}\right],{\mathbf{v}}_3=\left[\begin{array}{c}2\\ 3\\ 1\end{array}\right]$

Analysis of Candidate Vectors

• Linear Independence: The vectors ${\mathbf{v}}_1$ and ${\mathbf{v}}_2$ are clearly linearly independent as they span the x and y axes respectively.
• Assessing ${\mathbf{v}}_3$: To ascertain its linear independence, we perform a linear combination test. Upon inspection, it’s evident that ${\mathbf{v}}_3$ cannot be expressed as a linear combination of ${\mathbf{v}}_1$ and ${\mathbf{v}}_2$, confirming linear independence.

Conclusion: Yes, They Form a Basis!

Through rigorous analysis, we conclude that the vectors ${\mathbf{v}}_1$, ${\mathbf{v}}_2$, and ${\mathbf{v}}_3$ indeed form a basis for ℝ³. Their linear independence and ability to span the entire three-dimensional space meet the criteria for a basis set.
