# Thread: how to find vector from the vector space R³

1. ## how to find vector from the vector space R³

2. Which parts are you having problems with?

3. At least show some effort. What does " $\{v_1, v_2\}$" mean? Is it the span of the two vectors?

6. Later in the problem, they consider $\text{span}\{v_1, v_2\}$, so $\{v_1, v_2\}$ is probably just the set consisting of $v_1$ and $v_2$.
