find ` vecA xx vecB ` if ` vecA = hati - 2 hatj + 4 hatk and vecB = 3 hati - hatj + 2hatk`

Explanation

To find the cross product of the vectors \(\vec{A}\) and \(\vec{B}\), we will use the determinant method. Let's go through the solution step by step.

### Step 1: Write the vectors in component form
Given:
\[ \vec{A} = \hat{i} - 2\hat{j} + 4\hat{k} \]
\[
