Bhaiya I am in 11th std(began before 2 months)...Allen (latur,Maharashtra) Currently Trigonometry is going on in maths , I saw this question and came here , I didn't get the first step (when you added that 6 terms giving =6s)...can you explain
HMMT 2019 ( INMO prep nostalgia ).. My approach was based on cross product intuition. There's a specific identity in linear algebra that reduced the expression to the mentioned G.P ( around 5 minutes ). Btw, The reverse engineering of the thought process behind the question is beautiful . Isn't it?
Man people will generally advise you to study English for that matter but it doesn't really work.... Aap ek kaam karo advance ke pyq ko aur saare questions lo bas padhna shuru karo and ek notebook mei kuchh sentences ke implied meanings likhlo... Dheere dheere aapko idea lagna shuru ho jayega
Hi. Main kehna chahunga ki aapko words ke matlab toh pata hain but aapki time limit ke andar question ki sahi interpretation nahi ho paati. Yeh problem bahut saare teachers ke vajah se shuru hoti hai. Vo advanced ke problems class mein hi board par solve karwaate hain khud question aapko simplified language mein samjhaakar. But advanced ki problem ka pehla challenge uski language interpretation hi hota hai. Aap dheere dheere padhna start karo problem ko and ek sentence ko samajhne ke baad doosre par jaao. Hope this helps
As someone mentioned to study english, i dont think thats a good idea. It would be better if you start to read more of your theory, from ncert and other books. That will make your understanding much better.
Bhaiya 11 k lie bhi le aaiye S060 course. Hum jaise kuch desperate bchcho ka kaafi faayda ho jaayga. Jaise seq and series binomial trignometry aur quad k kuch bdiya q ka set.
@@Zerotoinfinityroad first u need to get that a,b,c are interchangeable in the denominator So like you can write ab(3a+c) as ba(3b+c) or ac(3a+b) Because it won't change the main meaning of the summation, the values of the variables a b c can be named c b a or b c a or bunch of combinations and the value of the main summation will not change so he took all the possible combinations of a b c that can be written in the form of ab(3b+c) and wrote them down and since each summations will be equal to the original summation named 'S' they are all equal so once when you add them all you get 6 times S which will be equal to a very nice eqn Explaining this was a bit difficult so sorry for any unclarity Hope this helps
Lekin jo summation ka operator hai usme order toh alag hai na,pehle c tends to fir b tends to aur fir a.toh yeh keh kaise keh sakte ki sabka sum 's' hoga?
Bro there is an error in this solution while summing is upto 6S the summation signs were diff(like c is in outer side in one of them while c is in middle in one of them) for all of the 6 cases as we got those via substitution by each other
You can interchange sigmas in any summation because of associative property Eg: (1+2+3+...) + (1² + 2² + 3² + ....) + .... Upto infinity Is the same as (1+1²+1³+....) + (2+2²+2³+....) + ...upto inf

What are you doing rn in life
can u tell me ur approach
Bhai ye kon c book me hai…
Book nahi, usne bola ki HMMT mein aya tha
What papers did you do of hmmt like individual or team rounds.

Your explaination is very best
just put a=b=c and solve, u will get the answer within minute
Amazing sir 👏👏👏
Can you explain if you understood it ,, just firt 2-3 steps
@@Zerotoinfinityroad first u need to get that a,b,c are interchangeable in the denominator
So like you can write

cuz this is a symmetric sum i guess thats why

Ohh, u mean order of summation would create a difference?
Let me check once!
You can interchange sigmas in any summation because of associative property

Is the same as

hello bhaya

aap kya 11th ke liye bhi laa skte ho koi course july end tk
pls thoda bahaut idea dedena jisse mai accordingly plan kr pau
Sir we can also solve by taking integral
Sir what should 11th graders do to develope their thinking process, do you have a course for them as well?
sir aap ek baar jee deke dekho na bas maje ke liye. sirf maths attend karlena and dekhna kaisa jata hai
HMMT 2019 problem a little bit modified
Bhaiya but if we input 2 in a,b and c then value becomes 2^13 then how is it possible that S = 54
bhai mera doubt ye hai ki kya hum a , b ,c ko ek hi term karle kyuki sab ka summation ek hai , jaise ki maine a,b aur c ko k assume kar liya?

He added s 6 times that simple , i solved this question by myself
Bhaiya set of 60 11th class ke liye hai?
Bhaiya quadratic equation ke questions nhi ban rahe hai kya karu questions bahut jyade tough hai
Yeah really
try maths unplugged and pray.
Chod de next chapter par badh ek chapter par mat atke rhe
Maths unplugged ka quadratic equations ka question solving session dekhle. Bohot achha h.
Naah bro don't advise him such a wrong thing
Quadratic is a very important chapter it will be used in further chapters
He should have completed that
Quite easy… especially if someone has done double summation problems before, it’s obvious that the numerator will eventually become 3(a+b)(b+c)(c+a)
Bro there is an error as while summing those 6 summitions the sigmas are in different order so you can't just sum up the expression in their input ........
No you can
@@Naman00010 it's like telling that the order of sigmas in above questions doesn't matter
@@MohitMimrot-bp8rx yes , it doesnt
@@MohitMimrot-bp8rxif we can seperate the factors then it will be independent of order as a,b,c are independent of each other can you explain more ?
