The covariant vector field is:

\(v_{i}\) = \begin{matrix} x+y\\ x-y\end{matrix}

What are the components for this vector field at (4,1)?

\(v_{i}\) = \begin{matrix} 5\\ 3\end{matrix}

Now I can use this information to solve the following:

\(\bar{V_\alpha}\)

But am unsure for \(\bar{V^\alpha}\).

I imagine it would be a similar approach with a few changes. Any help would be brilliant thank you
