Trouble with the proof of Cauchy convergence criterion

Why does the Ratio Test prove absolute convergence when the limit test does not?

How would you calculate a derivative of $ f(x)= \frac{\sqrt{x+1}}{2-x}$ by the limit definition?

Is it true that $ \lim_{x\to0}\frac{f'\left(x\right)-\frac{f\left(x\right)-f\left(0\right)}{x}}{x}=\frac{f''\left(0\right)}{2} $

If $V_n(a)$ counts sign changes in the sequence $\cos a, \cos2a,\cos3a,\ldots,\cos na,$ show that $\lim_{n\to\infty}\frac{V_n(a)}n=\frac{a}\pi$

Calculate the limit $\lim _{n \rightarrow \infty} \frac{[\ln (n)]^{2}}{n^{\frac{1}{\ln (\ln (n))}}}$.

Stuck on how to approach integral $\int_0^1x^n\log(x)\,dx$

An interesting limit: $\lim_\limits{n\to\infty}\frac{\sin 1\sin\sqrt{1}+\sin 2\sin\sqrt{2}+\sin 3\sin\sqrt{3}+\cdots+\sin n\sin\sqrt{n}}{n}$

$\lim\limits_{n \to\infty}\sqrt[n]{\{\sqrt{2}\}\{2\sqrt{2}\}\{3\sqrt{2}\}\cdot\cdot \cdot \cdot \{n\sqrt{2}\} } $

Calculating $ \lim_{x \to 0} (\frac{x\cdot\sin{x}}{|x|}) $
