Question

What is the coolest thing about mathematics you can show me?

Answer 1

e to the i to the e i o = e to the wau to the tau wau wau

Answer 2

vihart?

Answer 3

Yep :)

Answer 4

try and find out what my avatar means, thats my favourite thing about maths at the moment

Answer 5

Ok, I'll have a look.

Answer 6

\[\aleph_0<c\]

Answer 7

Ask those who really are into mathematics ....

Answer 8

i am realllly into maths

Answer 9

although i havent studied as much as FFM, he can probably tell you more cool things

Answer 10

how about nearly all numbers contain the digit 3?

Answer 11

ok, somebody has to type the most famous one\[\huge e^{\pi i}+1=0\]

Answer 12

Mathematicians ... they are crazy animals, they don't see things ... they see numbers everywhere.

Answer 14

Age calculation(see the attached pic)... ;-)

Answer 16

The coolest thing about mathematics is that it is very useful for lots of things. Calculate how planets move and rockets go. How to build computers and cars. How to do your taxes.

Answer 17

^I agree, but I still like seemingly useless things, like Cantor's work on infinity.

Answer 18

@eigenschmeigen , is that a statistic?

because 98% of all statistics are made up... :)

Answer 19

I can't clearly see @eigenschmeigen 's avatar clearly.

Answer 20

yeah, as far as I can tell his favorite thing is trigonometry, lol

Answer 21

I know he's smart and sharp ...!

Answer 22

@Zarkon you gotta participate on this one!

Answer 23

1+1=2

Answer 24

proof!

Answer 25

good answer

Answer 26

The proof is too awesome to share

Answer 27

:)

Answer 28

I also like Godel's incompleteness theorem
...just sayin'

Answer 29

I've always been a fan of the Strong Law of Large Numbers

Answer 30

the wiki article on that is making my brain hurt

Answer 31

sorry, was away helping!

its Eulers formula!

\[e^{i \theta} = \cos{\theta} + isin{\theta}\]

such a rich source of maths, and its where complex numbers and trigonometry collide!

Answer 32

i like how you cannot express the innocent looking integral:

\[\int\limits{e^{x^2}}dx \]

in terms of elementary functions

my maths teacher challenged me to evaluate that integral when i completed all the other challenges he set me.. wasnt happy when he told me i had spent hours attempting it in vain

Answer 33

will be sqrt(pi)

Answer 34

its weird, it uses the "imaginary error" function erfi(x)

Answer 35

if it had a negative exponent it would be sqrt(pi)
the other day experimentX and I did the integral\[\large\int_{0}^{\infty}e^{-ax^2}dx=\sqrt{\frac\pi a}\]

Answer 36

oh wait, it was\[\large\int_{-\infty}^{\infty}e^{-ax^2}dx=\sqrt{\frac\pi a}\]

Answer 37

LOL .. you still remember ... still that guy had provided the other solution ... it was great BTW did you check back???

Answer 38

yeah, I recommended a double integral in polar coordinates from the beginning, but I don't know how to actually do them :P

Answer 39

I had seen that method before .... it was great.

Answer 40

usually i abhor other coordinate system other than Cartesian.

Answer 41

really? I'd think that would be tough for a physics major to only deal in cartesian

Answer 42

I gotta bounce, catchya laters

Answer 43

cyaa

Answer 44

well we had cylindrical and spherical system in course ... and there were stupid tensors, i never understood those stuff.
