Covariant Tensor first order, and antisymmetric second order

[Telemachus]

Hi there. This is my first time working with tensors, so I have to break the ice I think. I have this exercise, which I don't know how to solve, which says:

If $$V=V_1...V_n$$ is a first order covariant tensor, prove that:
$$T_{ik}=\frac{\partial V_i}{\partial x^k}-\frac{\partial V_k}{\partial x^i}$$

Is a second order covariant antisymmetric tensor.

Now, in my notes I have this definitions:
A vector field V is a first order covariant tensor, if under a change of coordinates from $$x$$ to $$\overline x$$ it's components are:
$$\overline {V}=\frac{\partial x^r}{\partial \overline {x}^i}V_r$$

I think I should use this, but as I said, I'm starting with this, and I don't know how to work this out.

Any help will be appreciated.

Hi Telemachus!

$$T_{ik}=\frac{\partial V_i}{\partial x^k}-\frac{\partial V_k}{\partial x^i}$$

Write out the barred version of that equation, then use the chain rule to compare one with the other.

Thank you Tim.
