revised Evaluate $\lim_{n\to \infty}(\frac{1}{n+1}+\frac{1}{n+2}+\cdots+\frac{1}{6n})$
This is a question about the evaluation of a limit.

comment Approximating an $L^2$ function in the Riemann sense
@MartinArgerami I agree with Stefan. There is no problem because $f$ Riemann integrable implies $f^2$ Riemann integrable. However I have edited the question to be consistent.

How much close? For example $f_n$ equal to ?

comment A Haar measure via the Lebesgue measure on $\Bbb R^d$
@martini First I want to know if the way I read the problem is correct. Is it?

@martini $\mu$ is a Haar measure if is a nonzero Radon measure that satisfies that for all $x\in G$ and $E\subseteq G$, $\mu(xE)=\mu(E)$

comment Schwarz inequality and linear dependence
Look at the steps you follow to prove Scwarz inequality. Assume that you have equality. What do you get in the middle?
