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.

Thanks a lot @Vinayak Srivastava!

Looking cool! How did you make it?

- 3 weeks, 4 days ago

@Vinayak Srivastava's method

Record it, and convert it to .gif format

I recorded myself using Eucliea, an application in the Google Play Store. Try it out if you like...!

OK Thanks a lot!

P.S.: what's @Vinayak Srivastava's method XD?

- 3 weeks, 4 days ago

Its actually not a method, its copying!

- 3 weeks, 4 days ago

Excuse me? I drew it in Euclidea...

No copyright claims will fall on me

- 3 weeks, 4 days ago

Then its not my method! I usually copy things(I am lazy).

XD hahaha lol

The second line...

- 3 weeks, 4 days ago

OK got that. But what did you record? I mean, what did you use to draw the stuff?

- 3 weeks, 4 days ago

Eucledia, a geometry game in Android

Oh OK finally I understood! Thank you so much!

@Hamza Anushath, I believe that @Vinayak Srivastava's method arguement you had wasn't about copyright issues - it was just plain copying and reusing it! Don't worry, I got your back!

Thanks, but it is actually hard to perfect an animation

I wonder how @Mahdi Raza does it...

He/she must be very skilled

- 3 weeks, 2 days ago

@Mahdi Raza, can you share your method of how to perfect an animation to @Hamza Anushath, please?

- 3 weeks, 2 days ago

Most probably KeyNote, a Mac application in Mac, but I don't own a mac...

@Mahdi Raza mentioned that many times before...

I mean that I use an Android phone for Brilliant

Hold on...

- 3 weeks, 2 days ago

Yeah, it is hard it make an animation in a mobile device (excluding laptops here), but what can I expect?

- 3 weeks, 2 days ago

I think PowerPoint also works well. I asked him and he told me this. Sometimes, my animations look good using PPT.
