 Aug19 comment Finding $F(x)$ so that $F'(x) = e^{-x^2}$ I see. Examining the graph of $\exp(-x^2)$ I see that $f'(0)$ is indeed $0$ but did you surmise this a different way? Aug19 comment Finding $F(x)$ so that $F'(x) = e^{-x^2}$ Yes you are right. Thank you Aug19 asked Finding $F(x)$ so that $F'(x) = e^{-x^2}$ Aug19 revised If $\exp(itH) A \exp(-itH) = A$ for all $t$, do $A$ and $H$ commute? Finicky. Just put the title into LaTeX and put "for all t" into "for all $t$" Aug19 suggested suggested edit on If $\exp(itH) A \exp(-itH) = A$ for all $t$, do $A$ and $H$ commute?

So the middle quantity is bounded by $m, M$ and $f$ must take the value of some $c$ so that $f(c) \in [m,M]$, and so this necessarily means that $c\in [a,b]$?
