I'm Evan. I coach math olympiads in addition to being a PhD student. I made a Twitch stream one day because I was bored and I thought it would be funny, and since then I started uploading videos from there to this channel.
Also I guess I have some dance videos stored too or something.

Did you even solve it?
yes
Hi, Sir, Is AGEST unavailable, for some reason, right now?

There was a stream recently where you attempted this hard Malaysian tst geometry problem, will you upload the VOD to TH-cam?
A really similar problem has appeared in a 2008 Argentina MO
u are my goat bro
rizztastic
This challenge has gotten even more difficult, but I got thru all 8 levels. Trying the other challenges as well.
I can't believe how can I do this problems, no idea :<, pls give me some advance
Just by bijective imply t such f(t)=2 and it is easy to solve)))
You're a girl or a dude ?
Dear evan chen ...iam big fan of you...and i love you a lot...iam a student and study in grade 11 and i want to be a mathematician ...iam preparing my best for prmo...but bevause of lack of guidance i cannot do it properly iam studying geometry by your book on euclidean geometry...i want to ask you that which book i should do for covering the topicsnumber theory and combinatorics..❤❤plzz reply sir love from india ❤🎉❤😊
For number theory you can do Modern Olympiad Number Theory by Aditya Khurmi
Thank you soo much ❤
Bro are you from india

Hello Coach! I would like to ask if u have any online course for international student . Im grade 8. Thank you!
I only run one course, web.evanchen.cc/otis.html, but it accepts int'l students, however it is an advanced course.
a mock aime gave me sleep deprivation
it's just crazy that people had to do this and 2 other problems in less than 4.5 hours
bro do you type like that ..... seems more like Letting out all your frustration on the keyboard (like i do)
have you uploaded the solution to Christmas AMO 2022/3 somewhere?
Alas, no. I never got to writing that one up.
@@vEnhance Thanks for your reply! That's a shame, I didn't quite get the solution yet but it seemed very nice! Do you plan on going back to writing this clean? Would appreciate it a lot 🙏
@@vEnhance How do we arrive at the conclusion that the a_i's divide a_n from knowing that P_0 and P_d are palindromic?
Thank you Evan for posting these streams
is no one really gonna talk about his typing
Diamond?
where is the diamond?
stick to math dude lol
Omg my problem uwu and lmao i didn’t realize 3n²+1 also worked lol…
How did you come up with this problem?
How much Mohs would you rate this problem?
U already solved it
evan chen I wanted to ask you "when you should quit maths olympiad preparation " as I am not as smart to do well in mo and although I enjoy it , I just can"t solve problems , no matter how hard I try , so what would you recommend , should I leave it as clearly I am dumb?
What grade are you and what country

I’m curious how M = 0.5 • (p + a + c - a•c•p̅) is derived. Edit: I see now, I had forgotten that A and C are on a unit circle. The formula is only true when A and C have unit modulus, otherwise more terms are required. Neat formula, thanks for the video
Fun one thank you!
👏
We want more of these. This is the first video that i actually understood. ❤

Evan I really enjoy your content keep up mate
First view yeah❤
what do you think of lean 4 as a general programming language?
I recently discovered Typst. It turned out to be very convenient. But I haven't figured out yet, is it possible to track the changes made in an already compiled pdf file relative to the previous version?
The usual way someone keeps track of the history is to manage the code that produces the pdf, not the pdf itself. E.g. regularly copy your current code state and add the date in the name or even better : use git
Easy but u took time soo much its a 2 or 3 minutes problem
Nice 👍
