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.

Since it is a function with infinity zeroes it must a Weirstrass product but it seems it is discovered yet so I thought that in our free time,apart from real analysis,can least try and find one.Agree or disagree?

Just knowing what it is is not important. Applying it is more important. I'm asking you whether you understood how the manipulation was done, why it was done and what it led to.

I got it - the result is $\pi$ - which means $1$.

How?

$\frac{\pi}{\pi}$$=1$

So as you have agreed on the partners topic,what topic of mathematics should we deal first?

Log in to reply

I'm currently busy with Real Analysis. Mostly JEE related topics.

Can you explain a bit about it?

$\phi$ is the input of the function.

Can you look at my comment under your NIMO 2012 A1 problem, @Adhiraj Dutta?

Log in to reply

Do you understand the concept in that problem? When I was of your age, I didn't know what GP or summation was.

Log in to reply

Summation is the sum of the terms in a sequence (a series). GP is geometric progression. @Adhiraj Dutta
