maths question?

Question

what are the most important numbers in maths (or the single most important) whilst half asleep at uni one day i was told pi and e were the most important

i can understand why pi cos it appears so much but why e?

Answer 1

well i would try my best to give you real prefect answer ;

1- π ;3.14159265358979 or 32 digits (3.141592653589793238462643383...
---------------------
2- e ; 2.7182818284590452353602874713...
---------------------
3- Fibonacci Numbers ;
The Fibonacci Sequence!
1, 1, 2, 3, 5, 8, 13, 21, 34, 55, 89, 144, ...
---------------------.
4- ∞ ;Given the old maxim about an infinite number of monkeys and typewriters, one can assume that said simian digits will type up the following line from Hamlet an infinite number of times.This quote could almost be an epithet for the mathematician Georg Cantor, one of the fathers of modern mathematics. Born in 1845, Cantor obtained his doctorate from Berlin University at the precocious age of 22. His subsequent appointment to the University of Halle in 1867 led him to the evolution of Set Theory and his involvement with the until-then taboo subject of infinity.
--------------------
5- Perfect numbers;
The four perfect numbers 6, 28, 496 and 8128 seem to have been known from ancient times and there is no record of these discoveries.

6 = 1 + 2 + 3,
28 = 1 + 2 + 4 + 7 + 14,
496 = 1 + 2 + 4 + 8 + 16 + 31 + 62 + 124 + 248
8128 = 1 + 2 + 4 + 8 + 16 + 32 + 64 + 127 + 254 + 508 + 1016 + 2032 + 4064

6-Phi: That Golden Number;
---------------------

7- prime number ;
An integer p is called a prime number if the only positive integers that divide p are 1 and p itself. Integers that are not prime are called composite.Here are the first few prime numbers:

2, 3, 5, 7, 11, 13, 17, 19, 23, 29, 31, ...
-----------------------
8- Eban number; The eban numbers are the sequence of numbers whose names (in English) do not contain the letter "e" (i.e., "e" is "banned"). The first few eban numbers are 2, 4, 6, 30, 32, 34, 36, 40, 42, 44, 46, 50, 52, 54, 56, 60, 62, 64, 66, 2000, 2002, 2004, ... (Sloane's A006933); i.e., two, four, six, thirty, etc. These exclude one, three, five, seven, eight, nine, ten, eleven, twelve, etc.
-----------------------
9-The Golden Ratio;Leonardo Fibonacci was an Italian mathematician with a penchant for decimalization and rabbits! Having introduced the numbers 0 to 9 to Europe (like some medieval Big Bird from Sesame Street), he turned his attention to a different series of numbers:

1, 1, 2, 3, 5, 8, 13, 21, 34, 55......

The Fibonacci sequence is generated by adding the previous two numbers in the list together to form the next and so on and so on...
Divide any number in the Fibonacci sequence by the one before it, for example 55/34, or 21/13, and the answer is always close to 1.61803. This is known as the Golden Ratio, and hence Fibonacci's Sequence is also called the Golden Sequence. Unlikely though it might seem, this series of numbers is the common factor linking rabbits, cauliflowers and snails.

Fibonacci used his sequence of numbers to investigate the population growth of his favourite furry lop-eared friend, the rabbit. He based his model on a maximum-security bunny heaven where rabbits cannot escape or die, and the problem he devised goes like this...
---------------------
10- ' i ' ;The imaginary number takes mathematics to another dimension. It was discovered in sixteenth century Italy at a time when being a mathematician was akin to being a modern day rock star, when there was 'nuff respect' to be had from solving a particularly 'wicked' equation. And the wicked equation of the day went like this: "If the square root of +1 is both +1 and -1, then what is the square root of -1?" Previously, mathematicians had rolled their eyes skyward and prayed for divine intervention. But where others failed, the creative Italian Rafaello Bombelli triumphed with his invention of the imaginary number. The imaginary number is the square root of -1 and is known as 'i'.
-------------------
and at last
11 -666 ;
The Bible reference to the mark and the number (Revelation 13:18) has "the beast" forcing everyone to receive "a mark in their right hand, or in their foreheads" for all buying and selling. And of course, as every heavy metal fan will attest, the number of the beast is 666

well hope you enjoyed it . Good luck

Answer 2

Well e is also a number that appears a lot naturally in the nature. However, I would say there is no number as important as 1 in mathematics. From 1 you can get the rest, and actually that is how we really did it.

Answer 3

I kinda like i = √(-1) since, without it, you can't write
e^iπ + 1 = 0
which wraps all of those 'other' constants up in a neat little package ☺

Answer 4

e is used for natural logs. it is an important constant in engineering calculations.

Answer 5

Zero,

Answer 6

0,1,2,3,4,5,6,7,8,9 are the most important because they are in every solution every constant and so forth

Answer 7

0,1, pi, e , ........oh there was one more.
I just can't remember it.

Answer 8

pi+e=pie
mmmmmm.........

Answer 9

DON'T TAKE E AND STAY AWAKE

Answer 10

0,1,2,3,4..........9
