Re: Is this cool with you?

Hi anonimnystefy;

I ain't a teacher so I can not recommend a course of study. I say, "just let it rip!" Let your interests guide you. Skip what you do not understand right now and look at something that you do. Eventually, and I am still hoping, it will all come together.

Re: Is this cool with you?

hi gAr

actually i have started learning g.f's,but i don't have where to practice.

i started reading the 'generatingfunctionology' but i got stuck at the Fibonnaci sequence.

hi bobbym

my interests lead me to wrong things.

i know you are not a teacher,but if you were to give me advice?

i hope it will come together too.

Re: Is this cool with you?

I would have said the same thing gAr said! If you want to learn combinatorics and probability do not do it they way schools teach it. Mindless casework filled with NCR's all over the place. Learn gf's first! Everybody knows how to multiply polynomials!

Re: Is this cool with you?

Hi,

Maybe spend some time in a library with math books?
Quickly you can sort out what is boring or interesting!
Learn some programming too, that would make mathematics more fun!

Taking a break, see you both later!

Re: Is this cool with you?

hi bobbym

ok,g.f.s it is.

hi gAr

i can't go to the library to read math books because i need to read books for school,which is coming soon!
i never liked separating boring from interesting in math,because ,as boring as it is,that stuff might be useful.
i tried learning mathematica,but the comands look confusing!!!

see ya later.

Re: Is this cool with you?

See you gAr;

Everyone finds somethings less exciting or maybe even boring.

That is a necessity! Learn Mathematica! While you are a student you will be able to get it for nothing or for a ridiculously small price. With it you will learn to work problems in a new way.

Mathematica is not confusing. Ask someone! I have a computer math thread. If it is about a CAS then ask in there. Mathematica is not the only one, there is Sage, Maple, Maxima, Pari, etc.

Learn geogebra! An incredible tool. Follow the tutorials in Computer math.

Re: Is this cool with you?

Then you have it already. What the heck are you waiting for?

i have noone to ask

What am I? Monkey meat!

I have 4 rules for problem solving:

1) Ask mathematica.

2) Ask maple.

3) Ask geogebra.

4) Ask gAr.

Works every time!

Re: Is this cool with you?

That was sort of a joke but does have mucho truth in it.

Math curriculums teach you to work from the question to the solution. I always work from the solution to the question. This is confusing to grad students on up. It is not confusing to engineers who have coined the term "back engineer." You have the finished product or the answer, you have the question. How do flesh out what is in the middle?

Re: Is this cool with you?

Hi anonimnystefy;

You misunderstood. With the use of tools one can have the answer before the method. In industry here that is often the case. Very often they have the finished product. They would like to build more. Same principle.

Re: Is this cool with you?

Hi,

For 'n' persons guessing 'm' numbers with repetition from 'd' numbers, I found this to be close enough:

Hi gAr;

Is it closer than the previous approximation?

Re: Is this cool with you?

Hi bobbym,

It's the same formula generalized to 'n' persons. I have redefined the variables there.

E.g, when there are 2 persons guessing 8 numbers out of 32, the formula remains the same:

---

"Believe nothing, no matter where you read it, or who said it, no matter if I have said it, unless it agrees with your own reason and your own common sense"  - Buddha?

Hi gAr;

Oh I see, that is really good. I will have fun with that formula!

Re: Is this cool with you?

Hi bobbym,

For a closer value, it's better to go with:

Not very close, just a little difference.

Anyway, both are good enough for practical purposes!

How about if the n guessers choose different m's?
