হুম, আমি চাইসিলাম ডানপক্ষে যেন $|x-y|$ থাকে, তাই $(x,\frac{x+y}{2} )$ নিসি, যেহেতু মূল সমীকরণ x আর y এর জন্য সমরূপ, তাই, $(y ,\frac{x+y}{2} )$-ও নিসি এবং শেষে বাকীপদগুলা নিচিহ্ন করার জন্য $(\frac{3x+y}{4}, \frac{x+3y}{4}$ নিসি।

@dj দাদা,আপনার ১০ নম্বরে প্রথমে $n=0$ ধরতে হবে।
@মাহি,PDF এর সব ঠিক আছে,কিন্তু নিজের সামান্য পরিচয় দেওয়া উচিত ছিল না??
বড় ভালবাসি তোমায়,মা

@Mahi, Solutions of problem 1 and 6 have bug . When you use Muirhead, you have to consider all permutation (Both $a^{5}b$ and $ab^{5}$ )
@Dj and @Mahi, how to make a pdf file, and are you swift in typing (i'm very poor in typing )
You spin my head right round right round,
When you go down, when you go down down......

@Sourav: You can convert .tex file to .pdf online ( Try http://www.scribtex.com/ ). Also, there are many other software to compile latex files. But you need to write them strictly ( See here: http://en.wikibooks.org/wiki/LaTeX ) and those software are really huge!
I think the best option is to use TexMacs, Google it!

You can use Muirhead that way, if you just set them to be ordered and notice $MAX \{a_i\} \geq AM \{a_i\}$
This is more of a causality than a bug.

@Mahi: ( Both in problem 1 and Problem 6 ) Sourav was right. You can't WLOG set them to be ordered. You WLOG can only say, "either $a\ge b\ge c$ or $a\le b \le c$"
