Consider a Lagrangian $L:TQ\to \mathbb{R}$, for some smooth manifold $Q$. As explained in this answer, one can define its fiber derivative $\mathbf FL:TQ\to T^* Q$ as $$\mathbf FL(v) \equiv \mathrm d(L|_{T_x Q})(v,\bullet), \qquad v\in T_x Q.$$ More precisely, given $L|_{T_x Q}:T_x Q\to \mathbb{R...

I proposed an edit, two times on Find $\lim_{x \rightarrow \infty} \frac{\arctan (x^{3/2})}{\sqrt x}$. this question but both the times, It got rejected. For the first time, I ignored it. But it happened a second time too, on the same post. Editing a post gives $2$ points to the editor, which a...
