Hi;

I'd better not ask what a polynomial is, then!

Those are polynomials.

coefficients encode information about a sequence of numbers;

- indexed by the natural numbers

Hahahahahahhahahahhahahha! That is what I am talking about! Get the motor oil, I spot a pure mathematician! What a pretentious definition of a polynomial.

I'll have to leave it there, Bobby: bed beckonszzzz...

Catcha later.

'Mathspeak' *noun* : Math jargonese employed by self-opinionated pure mathematicians in an unintelligible, highfalutin manner for the purpose of self-aggrandizement.

My eyes glazed over when I saw what that pm wrote, and I didn't try to read through the smoke.

A couple of non-mathspeak examples of such obfuscation (loosely on topic):

- Where there are visible vapors having their province in ignited carbonaceous material there is conflagration.

- The person with the ultimate cachinnation possesses, thereby, the optimal cachinnation.

Hi;

Wikipedia is loaded with such guys. I once wrote a little piece for Wikipedia. Know what they did with it? They deleted it!

Hi Bobby,

Maybe you didn't use enough sesquipedalian words!

Did you crack the two "non-mathspeak examples" in my previous post?

After having been accused by the meanest woman I have ever known of being sesquipedalian, I found that page awhile back.

Hi bobbym,

What is the number of solutions to

a + b + c + d + e + f = 50 with a,b,c,d,e,f being positive integers and

a>b>c>d>e>f ?

A says) No solutions!

B says) 1057

C says) That is correct!

D says) No is isn't. The answer is 1058 by direct count.

E says) How did you get that B?

What is the correct answer?

Hi gAr;

Good to see you.

Both of those gf's are correct. Very good. Your second one is an improvement over mine, so I am stealing it!

Hi bobbym,

Thank you!

Yes, gladly! I was the first to steal, your g.f gave the idea.

How did you come up with that solution? You too thought of partitioning?

Hi gAr;

Actually, I was not thinking along those lines. I have in my notes the solution to various diophantine equations such as

I use them in the same way as I would use the quadratic formula. I never really thought about them.

Your idea is the first time I have seen any explanation of them.

Hi,

Okay.

I had tried the problem a while back, but was stuck with it. I'm happy that now we have a solution!

It's amazing the way the g.f's can be manipulated, wonderful!

Hi gAr;

They are truly amazing!

When I started learning combinatorics, I started with gf's first. So they are what I am used to and like. You know that I do not digest much theory. I learn by doing a problem and then trying to do a slightly more difficult problem of the same type. I know this is considered idiotic by the mathematical community and I take much ridicule on other forums. Unfortunately it is the only way I can learn.

Yes, that's the way I learn it too!

I read an example first to know whether it interests me.

Hi;

As you also know math types do not like to do an example. You can go through whole books where the guy never does a problem. These are the most difficult for me.

Hi,

Yes, I have seen such books. Some books where titles sound cool, but inside there will be no examples!

Hi;

Some mathematicians think doing a problem where you get a number is beneath them. They think that it is inferior in some way. Most according to Zeilberger still will not use a CAS. They think they are just toys.

Had a guy tell me that any integral or sum that a CAS could do, he could! So of what use are they? Of course I was laughing too hard to answer him.

They still teach gf's as if they are advanced mathematics, only for graduate students.

**New problem**

**In the drawing below each little circle has a circumference of pi units. They also meet at only 1 point with each of the two other smaller circles. The center of each small circle is on the circumference of the red circle.What is the radius of the red circle?**
