Hi everyone,

Spring is here, which means Proofathon has just posted the problem set for the Spring Competition!

The contest lasts 10 days, from 2/27/2015 to 3/8/2015. Be sure to log in or sign up at the Proofathon Website, do as many problems as you can, and submit your solutions to proofathon@gmail.com!

(PRO TIP: If you don't know how or don't have the resources to create a PDF with your solutions, here is an easy way: type up your solutions on Microsoft Word instead, and click the arrow next to Save As, and click PDF or XPS.)

Good luck to everyone!

~Daniel, Assistant Manager @ Proofathon

TopNewest@Daniel Liu Could you confirm if it's \( af(a+b+c) + f(bc) \) in Q3?

Because it seems like it should be \( bf(a+b+c) + f(ac) \) and also because the current question is solvable in like 2 lines.

I don't think it's even solvable as is.

Your dispute is valid. We will edit it ASAP (only @Cody Johnson can edit the PDF)

The problem should be fixed now; the error came from a typo. Sorry for the inconvenience.

But the date in pdf says it will run till 7th December'2015

LOL, that's (most probably) a typo. Cody quickly set up the PDF well past midnight, it was a long night for us yesterday. I'll ask him to fix it, and also add the names of the contributors.

How is the winner determined ?

Log in to reply

Winner is determined by people with highest score. We grade the solutions on a scale of 0-7.

But I don't think that I will be able to spare time to mail the solutions to you mainly due to the immense amount of time that I'll have to spare just in typing out the solution . Sorry about that , but I'll be a regular from the upcoming contests onwards :)

The reason for me not taking part is that I have my Board Exams(my National Examination) and JEE coming up .

Can you brief me about this contest? You see I joined Brilliant just in December so I guess I don't know many things that happen around here .

Thanks :)

Hmm, what information do you need about the contest? I am pretty sure I covered everything in this note...

You can find out more about the contest at the Proofathon Website.

I think i want to participate in this contest. But, is there any prize for the winner? I mean, some kind of book or whatever it is.

Top 3 get T-shirts and top 1 get Mathematica for 1 year I think. I don't really remember though.
