Find the unit vector of `4hati-3hatj+hatk.`

Explanation

To find the unit vector of the vector \( \mathbf{A} = 4\hat{i} - 3\hat{j} + \hat{k} \), we can follow these steps:

### Step 1: Understand the concept of a unit vector
A unit vector is a vector that has a magnitude of 1. To find the unit vector of any vector \( \mathbf{A} \), we divide the vector by its magnitude.

### Step 2: Write down the vector
Given the vector:
\[
