comment Largest possible 2D combination not containing 2 common rectangles
@GerryMyerson : I don't know how better to describe it, in case of 1D, consider a sequence, it is longest common sequence that can be found in more than 1 place in the sequence .

comment Was Euler right?
"Euler thought that", it was other way around , Euler was way ahead of his time in recognising what others could not even fathom let alone comprehend.

comment $\frac {\operatorname d\!y}{\operatorname d\!x}$ for $\sqrt{xy}=1$
You should search logarithmic differentiation, it makes hard problems really simple

and what have you done to solve this question?

I fixed up the latex for title, can you fix up the rest please?

comment Does sum of all natural numbers contradict another rule?
very well said, maybe even changing " are both meaningful in the appropriate context" to " are both consistent in the appropriate context"

What does $\log_{10} n$ gives?

comment Convergence of $\sum_{n=1}^{\infty}\frac{(\log n)^4}{n^2}$
@user121418 then try comparing it to the series for $\dfrac{1}{k^{1+\delta}}$, you know that series converges, then what can you say about this series that is smaller than the $\dfrac{1}{k^{1+\delta}}$ series?$\delta > 0$

comment How to work out an integral with algebra.
@LeoAzevedo : because we need to find $f(x)$ and $f(x+h)$. If it was an algebraic equation how do we find two unknowns with one equation?

comment How to work out an integral with algebra.
@hdh :as you can see, Algebraically no, this shows that is not possible. However that does not mean there is no way, only that there is no algebraic way. just like quintic equations that do not have algebraic solutions but have other methods for solution.

comment How to work out an integral with algebra.
@LeoAzevedo : Then that is the case of not having enough information. Indeed what more can be done?

comment Limit of Sequence n/(n+1)
+1 LOL, yes, the book is right, I would have said no, it is getting closer to 1. But it also is getting closer to $e,pi$ or any number greater than 1 for that matter. Very simple trick question to confuse the hell outta of people.

comment Details of $z=u \cos(v) \sin(u), u=e^{xy^2}, v=x^2+y \quad \frac {\partial z} {\partial x}=?,\frac {\partial z} {\partial y}=?$
@Potato : that is the perfect reason. Regarding not being able to click the links, is it a technical issue that has been passed on to the SE techs? I too want to see the limit of 150 chars to be lifted from math SE.

@Potato: I try to make them to be to the point, with least amount of characters. But if you can point me to an instance of making them being less descriptive would be good, as I strive to make the titles as descriptive as possible without needing them read the content. What is the issue with titles consisting of just symbols? I have seen many math articles with titles consisting of just symbols for their title. But I do what I can to keep as much as possible people happy.

comment Evaluating $\lim_{n\to \infty } \, \left(\sum _{k=1}^{\infty } \frac{1}{n}\right)$
@JLA : I added extra info at the bottom, in this case there is a limiting factor involved within each summand, that is what makes the usual defined version ambiguous in this case.
