comment What is the best approach when things seem hopeless?
Also, this approach tends to make the exercises a bit easier, atleast in my experience.

comment Is the derivative of this function bounded?
I think $f'(t) \leq C(f + f^(3/2))$ shows that $f'(t) \rightarrow 0$ as $ t \rightarrow \infty$. Because $f \in C^1$, we know that $f'(t)$ is continuous. This helps see that $f'(t)$ is bounded on some interval $(a,\infty)$. Is there a flaw in my reasoning here?

comment suggest textbook on calculus
@george: I am glad that you have found Titu's book helpful. I think it is also a good way for you to get introduced to analysis.

comment Quantum mechanics for mathematicians
I am using Takhtajan's book right now. Dirac's book is indeed very frustrating.

comment A problem about Field extension
I think people here will be generally more willing to help you if you show them that you've sufficiently thought about this question by telling them how you would go about or start the proof. Otherwise, it just looks like a homework problem you're just throwing at us to solve on your behalf.

comment Riesz Lemma to the Riesz Representation Theorem
Thanks Theo. Do you then think there is any point in proving the converse I stated above: for each y∈H, then there exists an unique Ty∈H such that Ty(x)=(y,x) ∀x∈H. ?
