Question
$23-25$ Find a unit vector that has the same direction as the givenvector.$$8 \mathbf{i}-\mathbf{j}+4 \mathbf{k}$$
Step 1
The magnitude of a vector is calculated by taking the square root of the sum of the squares of its components. In this case, the vector is $8\mathbf{i}-\mathbf{j}+4\mathbf{k}$, so its magnitude is $\sqrt{8^2+(-1)^2+4^2}$. Show more…
