Question

In Exercises 24-27, find ${\mathrm{comp}}_{\mathbf{u}}\mathbf{v}\mathbf{},{\mathrm{proj}}_{\mathbf{u}}\mathbf{v}$ and the component of v orthogonal tou.

Short answer

The values are and the component of v orthogonal tou is.

Step-by-step solution

Step 1. Given information.

The given vectors are:

Step 2. Find the component of the projection of v onto u.

Then,

$$\begin{gathered} {\mathrm{comp}}_{\mathbf{u}}\mathbf{v}=\frac{\mathit{u}\mathbf{·}\mathit{v}}{||\mathit{u}||} \\ =\frac{-1}{\sqrt{29}} \end{gathered}$$

Therefore, localid="1649675490199" ${\mathrm{comp}}_{\mathbf{u}}\mathbf{v}=\frac{-1}{\sqrt{29}}$.

Step 3. Find the vector projection of v onto u.

Therefore, the vector projection of v onto uis.

Step 4. Find the component of v orthogonal to u.

The component of v orthogonal tou is$\mathbf{v}-{\mathrm{proj}}_{\mathbf{u}}\mathbf{v}$.

Therefore, the component of v orthogonal to u is.
