Now just another ordinary stupid NEET. Abstract Algebra has always been my enemy, now I am trying to conquer it.

comment How find this limit $I=\lim_{n\to\infty}\sum_{k=0}^{n}\frac{\cos{\sqrt{\frac{k}{n}}}}{2^k}$
isn't $I \le 2$ ??

comment Geometric interpretation of a Taylor series like identity
you probably mean $f(0)$, BTW doesn't the interpretation work??

comment Solve for values that satisfies convergence of a product of two functions is infinite.
you need to show that this value tends to infinity as x tends to infinity $e^{\theta x - \log(x)^{\gamma + 1}}$ also note that $\lim_{x \to\infty} \frac{\log(x)^n}{x} = 0$

comment Solve for values that satisfies convergence of a product of two functions is infinite.
$x = e^{\log x}$ and $\theta x \ge \log(x)^{\gamma}$ for all $\gamma \in \Bbb R$ for some $x \ge X $

comment Where does this unit vector come from?
scroll this link a bit upwards ... use $r=1$ and as for $y$ note the direction.

comment Where does this unit vector come from?
given that you know the magnitude of vector and two angles (azimuthal and polar), you can decompose the vector into x, y and z components ... which is what you get as above.

comment solving $ \lim_{(x,y) \rightarrow (0,0)} \frac{\sin(x^2+y^2)}{x^2+y^2} $
use substitution $r \to 0 \implies r^2 \to 0$
