I'm just a single point on a complex plane. I'm not the strongest species that survives, nor the most intelligent, but the one most responsive to change. I always feel restless despite being in the safe zone. You can't teach me anything, but you can stimulate me to think! I am a detail-oriented analyst and interested in almost everything. Consistency, optimization, best-practice, & perfection are always my first priority in mind! Therefore by my questions & answers you'll fully recognize me. I can tell you more but then I have to kill you.

I distribute my rep in bounties as spending money for my & your pleasure is more meaningful than saving money in a bank & abandoning it unused.

"If you're an underdog, mentally disabled, physically disabled, if you don't fit in, if you're not as pretty as the others, you can still be a hero, read TEXBook!"

"Motivation isn't enough. If you've an idiot & you motivate him, now you've a motivated idiot."

Learning (La)TeX, PSTricks, & PGF/TikZ is similar to learning how to swim or drive a car. You don’t get the full benefit by watching someone else do it. Your own fingers must get involved.

Don't be lukewarm! If you cannot be the best, be the worst!

Beauty without intelligence is a masterpiece painted on a toilet paper.

For every problem, there is always a solution that is simple, neat, but wrong.

Best practices

  1. Use pdflatex \input{filename} instead of pdflatex filename.
  2. Don't specify the file extension in \includegraphics.
  3. Divide your project into a main & smaller input files & compile the main with pdflatex.
  4. Put each code snippet 4 either drawing a diagram or making a table into a standalone input file & compile it to produce a PDF.
  5. Define global macros 4 often-used materials, put them into a separate package thereby changing the macros in one place will effect the whole document.
  6. Remove unnecessary packages.
  7. Don't mix different series, families, font size, & shapes, ESPECIALLY IN ONE SENTENCE.
  8. Obey.

comment Is my theorem correct? $f(x) \leq g(x)$ for $x\geq a$ iff $f'(x) \leq g'(x)$ for $x\geq a$ and $f(a)=g(a)$.
what is the name of the well known corollary?

By assuming the right side is satisfied first and prove that the left is either correct or incorrect.

Could you prove in both directions?

I cannot show my effort to solve this problem. Is it necessary to show it?

+1. Makes sense!

But you can see 3 faces by focusing on one corner.

comment How to prove the number of images of two mirrors inclined at $A$ is $360/A -1$
+1 Short respons: I ask myself to prove it analytically. :-) I will give other comments later as I am teaching right now. :-) thanks.

OK. I am waiting for other solutions if any.

@heropup's solution in his comment seems to be much more better.

comment How to find the closed solution for the following recursive vector equations?
@heropup: I think it should be $\sqrt{k-1}$ rather than $\sqrt{k}$.

@heropup: You can submit it as your answer, but don't forget to write the process. I will give you a bounty of 500 if it is the only possible solution.

I will give a bounty of 500 for the first correct answer!

Note that I have updated the question in $\vec{r}_{n-1}\cdot\hat{v}_n=0$.

Length in the title but speed in the body, so what is the correct question?

Title and body are out of sync!

Make sure the question was correctly typed first!
