Step 1
Step 1: To find a+b, we simply add the corresponding components of the vectors: a+b = (-4i + 2j) + (-7i + j) Step 2: a+b = (-4i - 7i) + (2j + j) a+b = -11i + 3j Step 3: To find a-3b, we subtract 3 times the components of vector b from the components of vector Show more…

For each pair of vectors, find $\mathbf{U} \cdot \mathbf{V}.$ $$\mathbf{U}=-\mathbf{i}+\mathbf{j}, \mathbf{V}=\mathbf{i}+\mathbf{j}$$

Consider the two vectors, A = 15.5x + 33.5y and B = 5.3x - 15.5y. What is the magnitude of the vector A-B?
Nishant K.
For the vectors $\vec{A}$ and $\vec{B}$ in Fig. E1.22, use a scale drawing to find the magnitude and direction of (a) the vector $\operatorname{sum} \vec{A}+\vec{B}$ and $(b)$ the vector difference $\vec{A}-\vec{B}$. Use your answers to find the magnitude and direction of (c) $-\overrightarrow{\boldsymbol{A}}-\overrightarrow{\boldsymbol{B}}$ and (d) $\vec{B}-\vec{A}$. (See also Exercise 1.29 for a different approach.)
