Re: সাম্যাবস্থা
Vaia, why don't we see the problem from a different perspective. :roll: Suppose, there is a box with two strings attached to both sides of it. You and one of your friends are pulling it from both sides. Let, you are pulling it by $F_1$ Newton force, and your friend is pulling it by $F_2$ Newton forc...

Re: Theories (Day 1)
Vaia, sorry, I made a mistake.
The actual problem wrote :$s$ and $t$ have to be positive integers.
I read Theorem-1.5. But, in it $s$ and $t$ may be positive or negative integers.

Re: Theories (Day 1)
Well, Vaia, here's a beginner for you.
Problem: If $d=(a,b)$, then, could we PROVE that there exists integers $s$ and $t$ such that $sa-tb=d$ ? (This is a problem from Adler's Book. Although I know that this is true, I have not been able to prove it )

Re: a bunch of questions about bonds
Well, Tiham, this theory also suggests that if we could find a substance which is only held together by Covalent Bonds, then, it would have a very high meling point. We all know such a compound- DIAMOND , which is a bunch of carbon atoms held together by nothing except Covalent Bonds. And, it is kno...

Re: a bunch of questions about bonds
Tiham, you're question was, which bond is stronger-ionic or covalent ? The answer is (without any doubt) - covalent bond. I will provide logic behind my stand. I actually discovered it along with one of my friends. As you know, Ionic Bond is the bond formed from electrostatic force of attraction, an...

Re: Astro Olympiad...........
Well, Tiham , may be I am too late to answer as well. ;) But, I think you should check out a book named 'Elementary Astronomical Calculations' . It is sold by the Bangladesh Astronomical Association. It contains almost all the basic ideas of Mathematical Astronomy. But, some topics might go over you...

Re: Fly's Problem (Advanced)
@Tiham: Thank you for pointing it out. :) :) I have changed the previous codes to the binomial codes. I am actually new at working with LATEX, so, I do not know all the codes yet. Besides, I couldn't find the code of Combinations in the pdf 'latexhelp'. Ei jonnoe oi choramita korechilam. Thanks agai...
