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.
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 ❤🎉❤😊
@@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 🙏
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?
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
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?
I'm so dumb that I don't even know if even solved it or not or just written a mirror image of that equation. It was a joke right? or did he really solved it?
