2023 MIT Integration Bee - Quarterfinals

[@tolberthobson2610]

14:00 He TOTALLY CHEATED RIGHT THERE LOL

[@sk-702]

he tried again in the final answer but they didn't let him haha

For more integrals and solutions you can see the new book "MIT Integration Bee Solutions of Qualifying Tests from 2010 to 2023"

Why don't you use a good zoom lens when shooting from so far away? The blackboard is essentially unreadable. Too bad. If you don't have a good zoom (too expensive to buy a camcorder instead of recording with a smartphone with a very limited zoom?), ask friends sitting at the front to take photos of the 2 blackboards and regularly insert theses photos on the video. After all, we are here for pleasure, not for pain.

First integral of Chirag's round was similar to an integral from IIT JEE 2010 - the famous one about 22/7 - PI. The standard way is long division and u-sub. Interesting he decided to use trig sub and Taylor Series. Maybe it's all the physics coursework.

[@raveesh-dw2ci]

a better way is to expand the numerator then write it as x^4(1+x^2)- 2x^5 one term gets cancelled and all you have to do is put x2 as t for the second term of the integral way faster

[@sahil___jakhar]

yeah I did this with the same approach and that too in 1 min

I was quite surprised how could chirag loose that ?

Is there anyway that I can see how these integrals are actually done. Its very hard to see the board and it seems like they do a lot of the steps in their head

[@ガアラ-h3h]

They surely do dude all people who go to competitions do however math 505 has detailed solutions

[@RegisteredLate123]

Why did the green asian guy write +2023, because it can be in place of +c ???

[@NickKinzel]

They said in the first vid, the +C isnt nessisary, therefore any answer can be off by any constant. The +2023 was just for fun

[@龍陽-n7c]

Problem 1的答案應該是(7/10)-ln2

[@noway_911]

the asian dude in quarter final 2 cheated

[@lyndalekirk6883]

how

[@ericzhu6620]

his answer wasn't accepted anyway

[@C-AbhijyotiKhakhalary]

His way of joking

[@C-AbhijyotiKhakhalary]

Everyone saw him so...

[@noway_911]

@@C-AbhijyotiKhakhalary No. On the first question, he writes his answer, sits back and looks at Luke's board. At 13:40 and 14:00. Then he changes it to Luke's answer in the last seconds. He gets the point there. Looks a lot like cheating

[@HARIOM_MISHRA]

Give these questions to any jee students of India i bet they can do it easily

[@r4music220]

ya i got the log 2 one in 20seconds 🤣

[@Rey-vs9xf]

chirag falor, the guy who lost in the 1st round, is AIR 1 JEE Advanced and mains. sooooo ur wrong

[@r4music220]

@@Rey-vs9xf He meant these qs bruh, these were easy. The actual rounds are insane, this is nothing compared to that

[@Rey-vs9xf]

@@r4music220 but he said any jee student can do it when jee AIR 1 himself couldnt do it..
