Re: Bafflers?

Hi;

What does the above factorization combinatorically tell us?


In mathematics, you don't understand things. You just get used to them.

I agree with you regarding the satisfaction and importance of actually computing some numbers. I can't tell you how often I see time and money wasted because someone didn't bother to run the numbers.

Re: Bafflers?

That factorization isn't quite correct.

Well,
can be, for example, the number of passwords of at least 1 character and at most 6 characters that can be made from x characters, allowing repetitions.

Ah, okay. I thought you meant a tag like on SE.

Where did you get this problem?

The only thing coming to my mind is that multiplying by 1/(1-x) gives the gf of the partial sums of the sequence given by the rest of the gf.

Yes, that is correct. So obviously, I had seen or derived something about the throwing of two die.

Re: Bafflers?

What is a unit triangle?

A says) An equilateral triangle with sides 1.

B says) Obviously it is a triangle with the longest side being equal to 1.

C says) What is a unit?

D says) It is a triangle with an area that equals 1.

E says) I have never heard of it.

What do you say?
