1. The problem statement, all variables and given/known data

Given that the derivative θμ transforms as a covariant vector ,show that θμ transforms as a contravariant vector.

2. Relevant equations

3. The attempt at a solution
Does anyone know how i should go to prove it ?Is it just a trivial substitution ?

What are θμ & θμ supposed to mean exactly? Uf the problem is just to show that $\frac{\partial}{\partial x_\mu}$ transforms as a contravariant vector, just try an analogous proof to the covariant case in your image. If you get stuck, show your work.
