comment Calculate: $\lim_{n\to\infty} \int_{0}^{\pi/2}\frac{1}{1+x\tan^{n} x }dx$
You could try to split the integral into one over $(0,\pi/4)$ and one over $(\pi/4.\pi/2)$ and treat them separately with the Dominated Convergence Theorem.

comment subset relations among Sobolev spaces and their duals
That's a problem pretty much every one learning about Sobolev spaces seems to encounter sooner or later, see here.

comment The infinite-dimensional limit of sequence of solutions of linear equations when the number of equations goes to infinity
There is quite a lot of literature devoted to the question how and to what extent a bounded operator $C$ on a Banach or Hilbert space inherits properties of an approximating sequence $(C_n)_n$ of operators with finite-dimensional range. One can study questions like yours in the abstract framework of Banach- and $C^*$-algebras, see for instance Hagen, Roch, Silbermann $C^*$-algebras and numerical analysis.

comment Maximal ideal space of $C^*$-algebra of Riemann integrable functions
Thank you. You are right. I should have seen that. Do you know a reference where this construction is carried out?
