Orginal question: In a tournament of 98 competitors and each pair of competitors only play each other at most one. After some matches, for any 49 competititors, there's a competitor who has played all of them. Prove that there's at least one person who played everyone else
fast atlas
my calculations were about the same
Uhm... What?
fast atlas
Wait i think a proof of contradiction can work
If there are no degrees of vertex 98 then the graph has the most edges when 1 vertex is degree 96 and the rest are degree 97
In which case the number of edges is 4801 (i think?)
Then idk

For those who want, this is a fun question in the 2026 Catalan Mathematical Olympiads (yes it's because of the Spanish Olympiads being in 2026)
- Prove that, if $\alpha , \beta , \gamma \in (0,\pi /2)$ are angles of a triangle, the following inequality holds:
$\frac{1}{\cos \alpha}+\frac{1}{\cos \beta}+\frac{1}{\cos \gamma} \geq 3\sqrt{3}{\tan \alpha + \tan \beta + \tan \gamma}$

I remember seeing a solution to IMO 2001 P2 by contradiction
I found it and I wanted to share
A solution of IMO2001 P2 by contradiction:
,tex
Let $x=\frac{a}{\sqrt{a^2+8bc}}, y=\frac{b}{\sqrt{b^2+8ca}}, z=\frac{c}{\sqrt{c^2+8ab}}$ then $0<x,y,z<1$ and $\frac{bc}{a^2}=\frac{1-x^2}{8x^2}, \frac{ca}{b^2}=\frac{1-y^2}{8y^2}, \frac{ab}{c^2}=\frac{1-z^2}{8z^2}$\
thus $8^3x^2y^2z^2=(1-x^2)(1-y^2)(1-z^2)$\
Assume $x+y+z<1$ then:\
$1-x^2>(x+y+z)^2-x^2=(y+z)(2x+y+z)\
1-y^2>(x+y+z)^2-y^2=(z+x)(x+2y+z)\
1-z^2>(x+y+z)^2-z^2=(x+y)(x+y+2z)\
\Rightarrow 8^3x^2y^2z^2>(x+y)(y+z)(z+x)(2x+y+z)(x+2y+z)(x+y+2z)\geq8xyz.8^2xyz=8^3x^2y^2z^2$\
Which is a contradiction. QED

you should try the problem for long enough, giving up only when you think you've tried everything you could think of. When you fail a problem you should read the solution(s) and understand the motivation behind them, or learn the theory if they use something you didn't know
I don't know if there's any particularly enlightening advice on how to solve problems, you basically need to do a lot of practice and you'll slowly build the intuition to solve harder problems

(I was having lunch but now I'm back)
I don't know your level, if you're just starting out I suggest trying past papers from your country's Olympiad first rounds, and start learning through reading the solutions to the problems you didn't get. It's important not to feel discouraged when you fail a problem, because it's an opportunity to improve. I knew some people who were happier when they failed problems than when they solved them, because they could get to learn new insights from the ones they didn't solve
once youre confident with the basic stuff (if you're not already) it's mostly a grind. I think the "problem of the day" thing in the mods server (linked in the description of this channel) is really good
99% of the problems I did were potds from mods, or problems from egmo (the book) or mont

pallid tundra
1+…+8=36
half that is 18
each term of the expanded product you pick the sign of the exponent to be either + or -

Does anyone with Olympiad experience know how much theory is actually required at olympiads? From what I understand, Olympiads should only require some pretty basic results (AM-GM, Cauchy-Schwarz) but be used in creative ways, but as I’m reading worked out solutions to problems and various training camp handouts I’m seeing tons of ridiculous theorems and concepts ive never heard of (Muirhead’s inequality, Karamata’s, Majorization, Miquel Points, barycentric coordinates, etc.) and some of them just explicitly use linear algebra/calculus in their solutions (in Yufei Zhao’s handouts and Evan Chen’s worked out solutions). Are these techniques just helpful, or some of them things that you actually need for olympiads?
Basically what asking is how much theory does one actually need to know to tackle a majority of Olympiad problems

Anyway that looks hard 🥶
that's actually one of the easier ones
the property tan alpha + tan beta + tan gamma = tan alpha * tan beta * tan gamma holds for alpha + beta + gamma = 180
so it's really just an AM-GM
took me two fucking hours to solve it and i find it so fucking obvious
i did another approach tho
not really by AM-GM but by doing a more straightforward inequality
by 1/cos alpha = a and so on
so $a+b+c=3\sqrt[3]{a\sin \alpha + b\sin \beta + c\sin \gamma}$

i think the line gets drawn somewhere around linear algebra and calculus
but if youre talking olympiad olympiad then i think that like
there is some theory that is very nice to just know because it makes some problems a lot easier
/gives you more possible solution paths to go down
Olympiads should only require some pretty basic results (AM-GM, Cauchy-Schwarz)
i think this is roughly supposed to be true - i.e. olympiad problems are written around being "pure" or something
but the thing is that like
sometimes theory just makes a problem easier

I mean those are especially designed for ioqm and rmo exam with previous year papers and questions

Thing is
Im not very familiar with number theory and stuff
And everyone has different suggestions
So Im feeling a bit confused
radiant jasper
You can look for PDFs of the books or like samples of the suggested books.

So Im feeling a bit confused
well u gotta start somewhere. Don't think too much just pick a book and start it
radiant jasper
And choose one you are comfortable with
lethal gyro
I picked one pdf on nt
radiant jasper
So Im feeling a bit confused
I'd say Thrills and challenges of pre college mathematics is pretty good as it teaches everything from scratch
radiant jasper
But it doesn't have problems from ioqm or from their format
It focuses more on proof that questions
lethal gyro
Oh
radiant jasper
And its exercises are unsolved. So it can get pretty annoying
radiant jasper
Previous year questions
And similar exams
Also there's a lot of material online,you can look into them too.

it aint
but if theres something i learnt
i directly started with rmo stuff
and just ioqm amc pyqs
it helped me a lot tbh
and theres no way you can prep for rmo and inmo in 2 and 4 months
it requires a lot of time
radiant jasper
But if you start with rmo and inmo prep first. You won't be able to prepare ioqm properly due to different formats (one subjective, I e objective). Plus it's gonna get annoying real quick. Rmo and Inmo aren't easy

what matters is that you grasp the approach

i kinda disagree tbh
radiant jasper
TCPCM is a decent book it has basic problems too and some hards ones too
radiant jasper
rmo isnt that difficult, it just takes time to solve
For someone who just started preparing for Olympiads it isn't difficult?
I mean you should start with basics and ioqm problems and after that switch to remove and inmo
Rmo*
