thread_title: Useful citation to simplify integrals 

message: Removed this, since it is incorrect:
:\int_{-\infty}^{\infty} e^{-{x^2}/{a^2}} \cos bx\,dx=a \sqrt{\pi}(\sin{a^2 b^2 \over 4}+\cos{a^2 b^2\over 4})
Try numerically with a=b=1. Should probably be {a\sqrt{\pi}}
\exp(-({ab \over {2}})^2) for a>0. TB
:GENERAL REMARK: it is better to write x{sqrt(c)} than (sqrt(c))x, because it is prone to misunderstanding if the sqrt sign just does not stretch to include the x, or just does.
:Admittedly, this remark would be clearer if I had the "real" sqrt symbol available here, but you understand what I mean, I hope. My remark applies to the integral of the exponential of minus x squared, which results in the error function. Alex Vermeulen, The Netherlands Jordaan12 (talk) 15:35, 19 February 2010 (UTC)
thread_title: Removal of apparently incorrect integral

message: ive found a nicer looking solving of the integral
: \int x^n e^{cx}\; dx = \frac{1}{c} x^n e^{cx} - \frac{n}{c}\int x^{n-1} e^{cx} dx
wich to me looks nasty. i have a easier method. should i add it?
Yes please.  The solution is still an integral.  Aren't there any serial represantation of this integral. Or something nicer  —Preceding unsigned comment added by 88.229.24.154 (talk) 13:26, 19 December 2008 (UTC)
thread_title:  Nicer integral 

message: :\int_{-\infty}^{\infty} x^2 e^{-ax^2}\,dx=\frac{1}{2} \sqrt{\pi \over a^3}
is incorrect.  That's the answer if the limits were 
:\int_{0}^{\infty}
I've changed it to the correct:
:\int_{-\infty}^{\infty} x^2 e^{-ax^2}\,dx=\sqrt{\pi \over a^3}

thread_title:  Inaccurate Integral 

message: The page needs proofs. That is, for every identity a link to a proof should be included, perhaps by linking to a page which contains proofs directly, like:
<complicated integral> = <nice value> (proof)
Or:
<complicated integral> = <nice value> (proof)
Or perhaps using <ref>:
<complicated integral> = <nice value> [1]
To me most of them look doable, but I assume that to a layman this looks just like your average unreferenced article. Shinobu 23:27, 1 June 2007 (UTC)
replies: text: I am a new user to wikipedia, but I think I can so this, at least for some of these integrals. Might take a while though. If anyone wants to help out, that would be awesome. Going3killu (talk) 00:55, 14 December 2009 (UTC)

text: I personally disagree. I found the inline proofs with the 'show' and 'hide' rather distracting from what the article was talking about. I'm not going to remove them (I'm new and wouldn't want to hurt anything) but if others agree, maybe the proofs should be removed.Chessofnerd (talk) 02:05, 27 January 2011 (UTC)
replies: text: I agree with you, and I think that so does MOS:MATH ("... don't include them when they serve only to establish the correctness of a result").—Emil J. 11:52, 27 January 2011 (UTC)

:\int {x \over \sigma\sqrt{2\pi} }\,e^{-{(x-\mu )^2 / 2\sigma^2}}\; dx= \frac{1}{2} \mbox{erf}\,\frac{x-\mu}{\sigma \sqrt{2}}-\frac{\sigma}{\sqrt{2\pi}}\,e^{-{(x-\mu )^2 / 2\sigma^2}}

message: Some of this intergrals work with complex values of the constants, it would be useful if it can be noted in wich cases.

message: Working on a proofs page. Please just give me a while to get it up and going. Also, any feedback would be awesome. I might need help. Thanks. Going3killu (talk) 03:08, 14 December 2009 (UTC)
replies: text: Just in case you're not aware, there is an ongoing discussion of the value of proofs in Wikipedia at Wikipedia talk:WikiProject Mathematics/Proofs. Also keep in mind that proofs as separate articles must still conform to Wikipedia notability and verifiability policies.--RDBury (talk) 15:09, 14 December 2009 (UTC)
replies: text: Yes, I have been made aware of the problems associated with making a "proof page", and have scrapped that idea. Instead, I have decided to opt for a different approach, which is demonstrated on the second integral on the list. could you take a look at that, and let me know if that seems acceptable.
