Let's share nice integrals.
Here's the first one
I'll post a solution later.
Okay.
For example this inocent image

Dimensions: 100 x 75

An avatar is a small image that will be displayed under your username in your posts. It must not be any bigger than 80 x 80 pixels and 10240 bytes (10 KB).
Could be this changed a little bit?
Like 100 x 100 pixels and 40 KB?
Do we really need L'Hôpital's Rule?
What about if you multiply top & bottom by
?Okay.
It looks like we'll have to wait.
Hello
Is there a way that the Administrator may change the forum into a new one like MathLinks or using Invision Power Board or vBulletin?
He used the "Integration by Parts".
Another faster way it is to set
, then we get the derivative quickly.{\raise0.5ex\hbox{$\scriptstyle 1$}
\kern-0.1em/\kern-0.15em
\lower0.25ex\hbox{$\scriptstyle 2$}}
Or
{\raise0.7ex\hbox{$1$} \!\mathord{\left/
{\vphantom {1 2}}\right.\kern-\nulldelimiterspace}
\!\lower0.7ex\hbox{$2$}}
Does that make sense?
It is separable, try it.
Did you figure out if it's a Bernoulli or Ricatti's differential equation?
There're very simple.
The first one can be rewritten as follows:
Then all you have to do is integrate each side.
Show a picture, may be useful.
When its something of the form 4/[(x+5)(x+3)] dx, it usually involves partial fractions.
Well sometimes it can be avoided.
Not hard, it can be solved without integration techniques.
I know where you got this problem ^^
It's really nice, of course with a synthetic solution.
Not hard to find.
Did you try Stewart's Theorem?
I forgot to mention that don't post integrals which don't have a primitive function in elementary terms.
sec(x) - tan(x) + x + C?
Sorry, you have to show us your solution (I dunno what I was thinking that I didn't ask you that).
Show your solution too.
Why not just differentiate back and check? Also, is there any need to use blatantly sexist language?
Well, actually when I was writing I didn't realize of that.
If you don't mind, please limit to make all type of disagreeable commentary. There're forms and forms to request the things.
That's the incomplete Gamma function.
That's correct.
You can post the next one.
Amazing!
This will become in the best!
Man, that would be awesome!
Thanks.
I hope someone give an answer.
Is there a possibility to set a Math button?
I mean, a button which generates the tags [math] and [math]
