Math Principles and Misconceptions

[The Dark Master]

Can you by any chance tell me the properties and values of e? Ive heard of it and know its indefinite....
When you are doing 1/0, you're dividing 1 by nothing, so nothing happens to it. Wont i still be 1?

x/y=z
x=zy

If x=1 and y=0...

1/0=z
1=0z
1=0

The statement is always false, no matter what value of z you have. The expression 1/0 is undefined.

As for e, it is a special, "natural" number.

sum(1/n!,n,0,infinity)=e

1/0! + 1/1! + 1/2! + 1/3! + 1/4! + 1/5! + ... 1/n! + ... et cetera
1/1 + 1/1 + 1/2 + 1/6 + 1/24 + 1/120 + ... 1/n! + ... et cetera

I did not get a word of that but i do know e is a letter =P

Please read the big, gigantic, bold notice at the top of the first post on the first page. You may instead ask a question, which is as acceptable as provision of facts. Thank you.

The sum function aforementioned is supposed to take the sum of a sequence of terms that follow a certain pattern. Since I lacked a sigma, I instead put it in graphing calculator notation. In that notation, there are four parameters: the rule, the variable in the rule, the lowest number to be substituted, and the highest number to be substituted.

sum(1/n!, n, 0, infinity)

Take the sum of terms that follow the rule 1/n!, when n=0, n=1, n=2, et cetera until you reach infinity (which technically you can't).

you just reminded me with the "n!"

can you explain as to why for some odd reason 0!=1? it makes no sense given the function of factorials.
(4! = 4 x 3 x 2 x 1 = 24) so how can you do 0 if it stops multiplying at 1?

since 0! = 1 and 1!=1 too, can't that be said as 0!=1! and thus 0=1?

[General Veers]

Well, I'm not as sure of the workings of 0!

Let me show you a page specifically dedicated to explaining that: www.zero-factorial.com/whatis.html. The Internet has everything nowadays...

I thought a factorial (!) was X*X-1*X-2*X-3....so long as X was an integer over 0

GVNB mind introduce the fuzzy logic to me?

I've heard that it application includes rice cookers
I'd like to know the basics of fuzzy logic
But I fail to understand the wikipedia article of fuzzy logic

[Sandmaster]

it asked it I wanted to redirect to an article about a powerpuff girls episode. wtf is powerpuff girls!?

[General Veers]

I'm afraid I am unfamiliar with fuzzy logic...let me research that...

It seems that it is the analysis of qualitative input data, the assignation of quantity to each qualitative input, and the analysis of the data as quantitative data (which would allow computers and what not to do calculations for us).

We humans notice that some things are "not right at all" and "just right." We assign values from 0 to 1 to these qualitative descriptions (e.g. 0 for "completely unacceptable" and 1 for "perfect" and all numbers in between for all other descriptions in between).

But that's like a stretched line, in which the closer you are to 1 or 0, the same increase in how good it is will have a smaller effect (so it will be +.1 near the center and +.01 near the edge)
