I´m looking for a book with the proof of the result that says the associated Lie algebra of a Lie group $G$, let be $G_{Lie}$, is isomorphic to the tangent space $T_e(G)$, where $e \in G$ is the neutral element.
Let me said the chapter or theorem, not only the book, please.
Thank you all
Look at Introduction to Smooth Manifolds, 2nd edition by John Lee (great book). This is theorem 8.37, page 191.
