Hi Guys, I just want to say that JOMO 5 has started! Please reshare and tell your friends about it. You can check out the paper here. Please read the rules before starting
This discussion board is a place to discuss our Daily Challenges and the math and science
related to those challenges. Explanations are more than just a solution — they should
explain the steps and thinking strategies that you used to obtain the solution. Comments
should further the discussion of math and science.
When posting on Brilliant:
Use the emojis to react to an explanation, whether you're congratulating a job well done , or just really confused .
Ask specific questions about the challenge or the steps in somebody's explanation. Well-posed questions can add a lot to the discussion, but posting "I don't understand!" doesn't help anyone.
Try to contribute something new to the discussion, whether it is an extension, generalization or other idea related to the challenge.
Stay on topic — we're all here to learn more about math and science, not to hear about your favorite get-rich-quick scheme or current world events.

I've told all of my friends! This is going to be really fun but @Yan Yau Cheng could you go a little easy on the trig? After all, this is Junior. I just finished. :D
What ? I think the correct file(ques 2 problem fixed) is now uploaded on the website ..... All participants , we're sorry for that inconvenience , really!!
Arrgghh... I cant do this, the problems arent bad but it just takes too much to convert everything to PDF 's and everything, i barely have that much time. sorry!

We are sorry Sharky and all others for the inconvenience but there IS a problem in question 2 ....
We have edited the file and soon , the correct version will be uploaded on the website ..... Apologies for your time that it consumed unnecessarily .....
I am a problem writer at JOMO but i also feel that this one is easier than previous JOMO (of course feeling easy/difficult may differ among people) .... Go on , all the best ! Progress expected this time .......
I didnt attempt any of the contest. If u are saying of the previous combinatorics contest, then I admit my worst prepared topic is combinatorics, while my strongest topic is inequalities.. But, previous contest was also easy, but I didn't get a few. As for this contest, I got all ques but one till now.. R u taking in it? all the best then
We are sorry Bogdan and all others for the inconvenience but there IS a problem in question 2 ....

@Bogdan Simeonov@Sharky Kesa
After Triple-checking, there IS a problem in question 2, we are terribly sorry and we have edited the question.
@Finn Hulse You might want to resubmit for question 2 as well since you already submitted

totally agreed, especially since I just learnt basic trig only .-.

The 1st equation was previously xy+2x+3y=2 but it was supposed to be xy+3x+2y=2 so we've edited it now

Thank you!
Why is JOMO and Proofathon always together? Can you please colobrate time so that I can participate in both.
Arrgghh... I cant do this, the problems arent bad but it just takes too much to convert everything to PDF 's and everything, i barely have that much time. sorry!

Dude I finished in 40 minutes. :P

For question 2, I can't find any non-negative integer solutions for x, y and z. Did yours have any negative numbers?
Log in to reply
there are no problems to question 2, I double checked
Log in to reply
I'll check again.
I got a non-integral answer and I'm sure it's right...
Log in to reply
It asked for nonnegative integers. I got two solutions for the equation but both of them had negative integers.
Log in to reply
Yeah I know.

Don't worry for that now , we'll now allow word documents .... You may submit it as microsoft office Word document too !
I think this one is pretty easy ,, Nice job, All the best for all participants

Really? Last weeks for me was the easiest, this one for me was moderately tough.

The proof problems were a bit strange. No casework, no induction, not really much of anything! :P
I cannot find any non-negative solutions to Qn 2.Is there an issue in the problem?

Happened to me as well.

Oh yes I did! Thanks. :D
Could you please tell me what the edit to the question is? I am not able to access the new file.
Great problems and solutions in JOMO5! Looking forward to the next one.
