comment Can the gradient be expressed with contravariant components?
Isn't $V^*$ isomorphic to $V$ for $\mathbb{R}^n$? And if $V^*$ should be kept separate from $V$ then what does "every vector has both contravariant and covariant components that transform in predictable ways" mean if the gradient can't be expressed in basis vectors in $V$ and must be expressed in components with basis vectors in $V^*$.

comment Components of vector in dual basis transform covariantly
I don't understand the significance of saying they "live in the dual space".

Covariant basis vectors are the same as dual basis are they not?

comment covariant and contravariant components and change of basis
In the book it shows the direct transformation matrix on the left hand side whereas here you have it on the right side. That is what is confusing me.
