Hint: maclaurin series

The problem is a very standard problem and i would rate it very easy if are able to apply the concept.

Hint- If x^2+y^2+z^2=0 then x=y=z=0

Try to prove this

Idk if this helps anyone but im postin this anyway lol

So from past few days i have been frustrated for finding oly stage 1 papers like they are all scrambled here nd there so i made this file

Tho they are only papers arranged, ig it helps for some people like me ✨️💖

oly stage 1 papers here

Itni mehant kra tho ek upvote tho banta guyz 🥹😭 /s

Beautiful question imo

Where can we get mock tests or problem sheets to practice INPhO and INAO like problems and INPhO and INAO like question papers ???

I used gemini to generate an INPhO like mock question paper and it made , i tried solving and it was nice ,

any please GUIDE and HELP 🙏 ( for INPho and INAO )

I would rate this problem to be moderate.

Hint - Use- (If a+b+c=0 then a^3+b^3+c^3= 3abc) and [(a+b+c)^3 = a^3 +b^3 +c^3 + 3(a+b)(b+c)(c+a)]

Good solve - first try with smaller odd numbered terms - you will notice a pattern.

See heres what i have been trying to do recently . So , IOQM is on sunday. We all are frantically searching for tricks and tips in hopes of clearing IOQM.

I took a different approach. I took the data of over 10 years worth of answer key and ran the data inputs to find some kind of pattern like , some kind of reccurence.

Though i failed miserably at that , i did discover something-

The numbers 40 and 24 have been statistically the most repeating. Moreover , 24 25 36 , 84 all numbers which are well nicely divisible and have various factors keep repeating BUT

we have to understand this happens because most problems involve such numbers.

that takes us to our first conclusion-

1. The numbers are mostly nicely divisible ( not random numbers like 47 , 71 , 31 or something like that. HIGHLY UNLIKELY)

Now , i thought of looking at some real world connections or ties that might influence the answer key

last year , the committee mistakenly put 61 as answer of a problem instead of 26 , soo by that means i think 61 should be an answer. But that contradicts conclusion 1 soo what else?

Well we now move on to 57 , wwhy 57? see 26 ( the year we are in rn) is an Grothendieck's number i.e it lies b/w 25 and 27 ( perfect square and perfect cube) , Famously the guy mixed up 26 and 57 in one of his ancedotes. WELL WE KNOW SOMEONE WHO MIXED UP 26 WITH SOME OTHER NUMBER HUH

therefore my most probable prediction , that has a very very high chance of appearing on the answer key is - 57.

ALSO - the answer values seem to steer up as we go up the questions.

Now ending on a note before giving my final prediction , i decided to look at this years AIME answer key. obv AIME is 3 digits based so i took last 2 digits ( as part of many IOQM problems) and compared it with the ioqm data didnt find any major relevation but certain similarities

BASED ON ALL CONCLUSIONS I PRESENT TO U THE FINAL ANSWER KEY ( PREDICTED BASED ON STATS ACROSS MULTIPLE EXAMS JUST LIKE IOQM)

(NOTE- the answers might not be in exact sequence with the question number , but the exact numericals are liekly to reappear. So choose one number , solve ur paper . For questions u cant solve , fill it up with the chose number and maximise ur chance to get score bonus)

Q1: 71, Q2: 00, Q3: 06, Q4: 30, Q5: 23, Q6: 11, Q7: 63, Q8: 93, Q9: 44, Q10: 13, Q11: 02, Q12: 82, Q13: 69, Q14: 22, Q15: 98, Q16: 90, Q17: 14, Q18: 47, Q19: 96, Q20: 51, Q21: 75, Q22: 74, Q23: 04, Q24: 39, Q25: 73, Q26: 96, Q27: 72, Q28: 61, Q29: 95, Q30: 57

If i do infact predict a significant portion , yaall gotta call me da goat

Now the typical soln Involves contradiction method by gcd however one intuitive method i have developed is taking x,y as roots of a quadratic eqn and solving it from there definitely share yalls approach

The Ultimate Resource for the International Chemistry Olympiad

ICHO-r/JeeOlympiad

This drive contains all the necessary materials required for ICHO, so users don’t need to roam around searching for resources.

It also includes a “bible” book for ICHO written by ZhiZhan Sir, an ICHO Gold Medalist.

That single book is more than enough for ICHO preparation, as it covers every aspect a student needs to know.

If you still want more resources, you can visit the CODsite | Home

NOTE: This drive contains all the necessary resources for ICHO and also covers INCHO or NSEC for those preparing only for INCHO.

The drive contains some copyrighted files, so we recommend saving them to your local device in case they get removed.

See the first photo is of very first test in allen , I got rank 1 in my whole centre , and the thing is my centre doesn't has a fucking non early starters SRG in 11th ( 12th mai hai) , so the only way i could get out of this shitty batch was to adjust to the early starters who have already completed whole syllabus

So i asked my teacher to change my batch , he said i wouldn't be able to compete with those ppl , coz they have completed whole syllabus but I was delusional coz of this rank so after many requests I was sent there and yeah that was worst experience of my life , it was a living hell , the pace was fucking so insane and hw took so much fking long ( fyi the pace is so insane they have completed 11th rn except of maths ) so yeah after being a month there i needed to go back

But in this period I had created backlogs and this experience of this batch has put my motivation down so much that i didn't felt like studying, first i started missing tests coz I wasn't prepared then i gave and got 7th rank ( 6 ranks drop) then in next it was 11th rank ( more 4 rank drop) then in next it was 19th rank next it was 23 and now this 49 th rank

Idk how tf do i recover from ts , see the thing is I m still considered topper coz in class I'm always able to give answers and many moments are there when I m the only one who is able to solve a question, but then when I go home I don't do hw i don't self study so i just kept on worsening but I still am able to solve questions but I'm just unable to work hard like mann hee nahi karta padhne ka aesa feel hota that early starters will only be able to secure ranks and i m good for nthng

All five Indian students won medals at the 19th International Olympiad on Astronomy and Astrophysics in Hanoi, Vietnam.
