Answer 1

Keep going please

Answer 2

And ... ? (:

Answer 3

my best guess is that it's is inverse hyperbolic sine but I don't know much about it

Answer 4

Answer 5

I need a solution to this. I know what Wolfram Mathematica able to do.

Answer 6

Easy bro

Answer 8

Thank youu .These tho words made me happy

Answer 9

Actually i saw that video before . Bur This isnt my question.

Answer 10

The denominator is sqrt(1+x^4)

Answer 11

@Hero ? What is the easy thing?

Answer 12

The integral

Answer 13

Make me think it's easy then (:

Answer 14

use euler integral

Answer 15

Bro, all you have to do is apply the elementary methods .

Answer 16

What are they? I cannot read your mind @Hero

Answer 17

Help me guys . I trust you

Answer 18

this can not be solved by any elementary method, you will have to apply euler integral.

Answer 19

Hero ? What do you think about it?

Answer 20

You told me it's easy. You told me that all i have to do is to apply elementary metods to solve the integral. Now what should i do?

Answer 21

If you know something spell it (: Come ooon

Answer 22

I think you should figure out why it's so easy

Answer 23

Which method should i use? Integration by parts ? Subtitution? I'm trying .You are not helping me

Answer 24

I beleive you're not serious Hero

Answer 25

I guess "hot-air method" is being applied

Answer 26

Sorry, I am busy so I am a bit distracted at the moment.

Answer 27

yep, hot air

Answer 28

@modphysnoob Could you apply that method for me? Because i dont know how. I never heard of it

Answer 29

There's no such thing as a "hot-air" method @integralsabiti

Answer 30

And @modphysnoob...shut up

Answer 31

That's fantastic

Answer 32

Sorry to disappoint you bro

Answer 33

And you? Is there such an ''elementary method'' to apply?

Answer 34

Apparently not

Answer 35

Thank youuuu

Answer 36

hot air method involved pretending to know a solution while not having a clue; like @hero did

Answer 37

@modphysnoob, you're so full of yourself. Get a life bro.

Answer 38

No fighting guyss .We re all brothers

Answer 39

@hero, no need for personal attack; that just shows your character

I was just pointing out to the fact that you act as if you knew the solution but didn't; resulting in wasting of others time. To be frank, I still do not understand the purpose behind your posts in this thread as you weren't even attempting to help.

Answer 40

@modphysnoob, there's no need to state stuff you don't know what you're talking about. You talk about my character, but you don't mind insulting me.

Answer 41

You didn't help the user understand anything by the way.

Answer 42

while I didn't help the user attained the solution, I did try ; unlike you posted
"Easy bro". "I think you should figure out why it's so easy"; but at the end, admitted that you didn't know.

Answer 43

Oh maan. I get the ''hot-air '' thing noow. I am an idiot.

Answer 44

That's what you interpreted, but that's the the reality. You mis-interpreted what I meant by "easy".

Answer 45

I meant that it is easy to see that it cannot be solved using elementary methods.

Answer 46

That's what I wanted @integralsabiti to figure out.

Answer 47

But you blurted it out

Answer 48

Ok guys i really appreciate your effort. Just stop it :)

Answer 49

@modphysnoob doesn't know when to stop.

Answer 50

Thank you Al Pacino. Now let's moove

Answer 51

@hero, nowhere did he that he is looking to solve using elementary method; by saying something is easy because it can't solve using easier(elementary) way is absurd, naive,uneducated.

Answer 52

@modphysnoob, Just more insults. Why don't you just go find an altar to sit on and exalt yourself

Answer 53

You both tried to help .And that means a lot to me. But you couldnt. Admit it .

Answer 54

No, I was mostly distracted and mis-spoke. @modphysnoob is being a real jerk though.

Answer 55

Leave me alone .Imma cry here

Answer 57

hey guys no need to fight over a question:) and modphysnoob is right:)

Answer 58

woah guys, chill... @modphysnoob is right no need to fight bout it @Hero

Answer 59

i agree with that:)

Answer 60

I don't recall fighting about anything. I was stating my opinion and thoughts regarding the matter. Fighting implies using fists and elbows.
