Contravariant and Covariant Vectors | 2/2

In this video, I define contravariant and covariant vector components. Here, we define contravariant and covariant vector components according to their transformation definitions. I also define invariants, which are quantities with intrinsic significance.

I describe two examples of contravariant and covariant tensors. For contravariant tensors, I use the tangent vector of a parametric curve. For a covariant tensor, I use the example of a gradient vector of a scalar field.

Questions/requests? Let me know in the comments!
