Question
True or false: If $\|\mathbf{v}+\mathbf{w}\|=\|\mathbf{v}\|+\|\mathbf{w}\|$, then $\mathbf{v}, \mathbf{w}$ are parallel vectors.
Step 1
This equation states that the norm (or length) of the vector sum $\mathbf{v}+\mathbf{w}$ is equal to the sum of the norms of $\mathbf{v}$ and $\mathbf{w}$. Show more…

True or False. If u and v are parallel vectors, then u x v = 0.
TrueβFalse Determine whether the statement is true or false. Explain your answer. If $\mathbf{u}$ is a unit vector that is parallel to a nonzero vector $\mathbf{v}$, then $\mathbf{u} \cdot \mathbf{v}=\pm\|\mathbf{v}\|$
