Post your queries and issues with the Mathathon 2021 here.

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.

Hi @Percy Jackson, When will the final problem be posted?

- 4 months ago

Posted. Sorry, I really messed up the schedule. All problems are here now.

Okay... but IDK how to solve integrals. Can I take some help?

- 4 months ago

When will the results be posted??

- 3 months, 3 weeks ago

Still waiting, @Percy Jackson

- 3 months, 1 week ago

Can we write on paper and send a scanned photo? Don't worry, my handwriting is legible :D

- 4 months, 2 weeks ago

Sure, anything is fine as long as is understandable. You will have to draw diagrams if necessary. Points will be awarded accordingly :)

- 4 months, 2 weeks ago

Okay

- 4 months, 2 weeks ago

Also, can we code the answer??

- 4 months, 2 weeks ago

Yes, but a proper solution will gain more points.

- 4 months, 2 weeks ago

Any extra credit for both?

- 4 months, 2 weeks ago

Not unless your code solves the problem in a unique way. Then extra Ingenuity points will be given. Otherwise no.

- 4 months, 2 weeks ago

Okay

- 4 months, 2 weeks ago

What is the estimated "portion"?

- 4 months, 2 weeks ago

I don't know things like integration, but I do know trigonometry, for example. So if I do not post solutions for such problems, is it fine?

- 4 months, 2 weeks ago

Yes, but you will lose those points. Questions will not be too difficult.

- 4 months, 2 weeks ago

Okay

- 4 months, 2 weeks ago

Math. All math. Algebra, Geometry, Probability, Trigonometry, Calculus etc. Don't worry about the last two, most will be Algebra and Geometry problems. You can try the sample problem i posted :)

- 4 months, 2 weeks ago

Yeah, I did that. But my solution was similar to yours, so I won't post one until I find a good way!

- 4 months, 2 weeks ago

I would love to participate but I’ve just found out about this today, is it too late ?

- 4 months, 2 weeks ago

I am sorry but yes, the participant limit has been reached. I will ping you if anyone wants out of the contest :)

- 4 months, 2 weeks ago

Reassure me : during the mathathon, answers posted by competitors won't be available for reading before April the $2^{nd}$.
Is that true ?

- 4 months, 2 weeks ago

No, the problems and solutions will be open to everyone on brilliant.org.

- 4 months, 2 weeks ago

So, how do you prevent a competitor "to be inspired" by already posted explanation ?

- 4 months, 2 weeks ago

I don't. If a competitor tries to give a similar answer to an already posted clever answer, they risk being caught because of the similarity, or risk losing clarity points due to not being able to replicate the answer. If they understand the concept clear enough to properly replicate a solution, shouldn't they be smart enough to think of it in the first place? That way, they risk losing even more points trying to copy ans answer, and that is why most won't try that. As such there is no way I can prevent others from seeing your solutions in a contest, unless I shared my email, which I would rather not :)

Did I miss something, or have only three problems been posted so far?

- 4 months, 1 week ago

Only three, I was a bit busy, I will post the rest today.

- 4 months, 1 week ago

Hi, where have the problems been posted ??

- 4 months, 1 week ago

Only 3 have been posted so far. You can find them in my profile or in the Mathathon links page.

- 4 months, 1 week ago

Where have they been posted ??

Thanks. When i asked the second time, i did not see any reply. Thanks once again !!

- 4 months, 1 week ago

Okay, no problem :)

- 4 months, 1 week ago

Hi! With everything you have to do, I just wanted to point out that the problems 4-5 are on your profile but not on the Mathathon links page. Keep up the good work, you are amazing!!

Hi Percy, I may not be available until this weekend :( if you are to give points before that time I may have to just quit halfway through :P

- 4 months ago

Today is the last day to post your solutions.

Well you can give points now :) I’m posting the rest at the weekend :) I’ll just quit now :/

- 4 months ago

Okay

I would like to participate

- 4 months, 3 weeks ago

You have been added sir :)

@Percy Jackson In problem 7, is the angle given between the ground and the birds line of view or between the tree and the line of view.

- 4 months, 1 week ago

Angle of depression from bird to the lion and elephant. Try to draw a diagram, it will be clearer.
