You aren't going to finish with that awful Colonel story?

Feels good to have everything ready cause you've already did it?

The front end in Mma is confusing. He needs to learn its capabilities.

He should change his screen precision. Six digits are for children.

Shift - Enter line 3 again and again.

In an iterative root finding process, we start with some seed value and try to improve upon that answer with each iteration, i.e, everytime we touch that value. We do so until the solution is satisfactory to some level of accuracy.

It's better to say a guess.

Hello:

Formula for an arithmetic sequence nth term.



{30,28,26,24,22,20,18,16,14,12,10,8} are how the seats are put.

Hello: I think that answer is too much. If you simulate it you will agree.

I missed the post too sad Thanks Relentless.

I didn't simplify sad

I know about Confucius I told you that.

Do you think that Geogebra used a least squares fit?

Mr. m, it looks like you have forgotten the definition of a sector.

What is ETPI?

I can only write a MonteCarlo simulation

ETPI - Exploit The Problem Itself

A simulation is enough for an ansatz smile

Hello Agnishom!

There are ways to solve problems.

i) ETPI ( patent to bobbym ).

ii) Apply Experimental Math to it.

iii) Ask bobbym when the old guy is in a good mood, like after he watches the Walking Dead.

I'll bet you can figure which I chose.

Hello:

I think I would want more explanation. What is a set of 4? smile

The official answer is correct.:)

I managed to find numbers 3, 30, 410 for the three smaller boards,

Which 3 and can you get a 4th one?

Hello

Bobbym had to prepare dinner for three so he's going to be busy for a bit.

His method was to accurately compute the first 10 rhombuses and then curve fit which needed an ansatz that only he could see. This won't be the type of classical answer you require but at least you have the answer. smile
