Find the values of a and b so that vectors `vecA and vec B` are parallel to each other .
`vecA=2hati+3hatj-4hatk`
`vecB=3hati-ahatj+b hatk`

Explanation

To find the values of \( a \) and \( b \) so that the vectors \( \vec{A} \) and \( \vec{B} \) are parallel, we can use the property that two vectors are parallel if the ratios of their corresponding components are equal.

Given:
\[ \vec{A} = 2\hat{i} + 3\hat{j} - 4\hat{k} \]
\[
\vec{B} = 3\hat{i} - a\hat{j} + b\hat{k}
