Chapter 1, Problem 43P

(a)

To determine

The vector expression for $\overrightarrow{A}$ in unit vector notation.

(b)

To determine

The unit vector expression for a vector $\overrightarrow{B}$ is one fourth length of $\overrightarrow{A}$ pointing in the same direction as $\overrightarrow{A}$.

(c)

To determine

The unit vector expression for a vector $\overrightarrow{C}$ is three times the length of $\overrightarrow{A}$ pointing in the direction opposite the direction of $\overrightarrow{A}$.
