manifold bases

[ehrenfest]

1. The problem statement, all variables and given/known data
I am trying to show that
\vec{e'}_a = \frac{\partial x^b}{\partial x'^a} \vec{e}_b

where the e's are bases on a manifold and the primes mean a change of coordinates
I can get that \frac{\partial x^a}{ \partial x'^b} dx'^b \vec{e}_a = dx'^a \vec{e'}_a from the invariance of ds but what should I do next?


2. Relevant equations



3. The attempt at a solution

You're dealing with coodinates bases, or else your expression above isn't true. Thus

\vec{e}_b = \frac{\partial}{\partial x^b}

\vec{e'}_a = \frac{\partial}{\partial x'^a}.

Yes, I am dealing with coordinate bases.

How can you set a basis vector equal to a partial derivative operator?
