Talk:Lists of integrals

message: My 25th ed. of the CRC Standard Math Tables is clearly authored by William H. Beyer and not Daniel Zwillinger. Should this be mentioned in the references section? --M1ss1ontomars2k4 (T | C | @) 15:11, 25 June 2006 (UTC)

message: I would like to know the integral for finding the volume of a section of a cylinder, such as a tank containing a liquid.  (If I have a tank r=48" and length=96" and I want to know how many gallons are in the tank at say 20" deep).
If it's a cylinder then you don't need an integral, just use the area of a cylinder formula.RageGarden 05:19, 24 April 2007 (UTC)

message: Hi,what about adding another section - list of definite integrals? 
I think it would be very helpful. —The preceding unsigned comment was added by 147.231.80.128 (talk) 07:03, 3 May 2007 (UTC)
thread_title:  List of definite integrals? 

message: The merge tag has been there since Jan 07, with no discussion.
I support the merge as it would put the most common integral which many people will be looking for in an easy to find place. --Salix alba (talk) 18:30, 13 May 2007 (UTC)
replies: text: Ditto for me. I intuitively searched for "tables of common integrals" first, as I was an old CRC bible user. The keyword "table" should force a redirection to the "lists" page. The most commonly needed integrals could be prominently placed. --MxBuck 16:09, 5 November 2007 (UTC)

thread_title:  Merge? 

message: If there was anyone interested, something that I think would be neat would be to be able to click on any of the formulas from the list of integrals and get redirected to another page with the proof on it.  It would be a lot of work, but if someone really liked math, or was bored enough, they could do it.  —Preceding unsigned comment added by ArthurJohnJones (talk • contribs) 20:42, 9 January 2008 (UTC)

message: I noticed sometimes arc* is used and sometimes *^-1 is used. Is there a particular reason for this? --Snaxe/fow (talk) 16:44, 24 April 2008 (UTC)

I don't think this is a good primary (or even secondary) reference.  This is just review material (essentially a collection of knowledge and formulas, sometimes without context) for people who want to take the licensure exams for engineers. Iccruz (talk) 03:06, 11 August 2008 (UTC)
thread_title:  References 

message: I question the title of the section Lists of integrals#Composed functions. The integrands are products of trigonometric and exponential functions. This is not what I would normally think of as composed functions. I was expecting the section to have something like
:\int{\exp{(\sin{(x)})} \, d x} \,.
Can we not think of a better title? JRSpriggs (talk) 01:23, 21 February 2011 (UTC)
replies: text: I see that Xanthoxyl has renamed the section Lists of integrals#Products of functions proportional to their second derivatives. This is more accurate, although cumbersome. Perhaps it is the best we can expect to achieve. Thanks! JRSpriggs (talk) 10:55, 21 February 2011 (UTC)

message: in the section "definitive integrals lacking closed-form antiderivatives" one finds this formula
:\int_{-\pi}^\pi \sin(\alpha x) \sin^n(\beta x) dx = \begin{cases}
(-1)^{(n+1)/2} (-1)^m \frac{2 \pi}{2^n} \binom{n}{m} & n \text{ odd},\ \alpha = \beta (2m-n) \\
0 & \text{otherwise}
\end{cases}  
and the next one
:\int_{-\pi}^{\pi} \cos(\alpha x) \sin^n(\beta x) dx = \begin{cases}
(-1)^{n/2} (-1)^m \frac{2 \pi}{2^n} \binom{n}{m} & n \text{ even},\ |\alpha| = |\beta (2m-n)| \\
0 & \text{otherwise}
\end{cases} 
Where does the variable m come from? How is one supposed to use the formula not knowing that?

thread_title:  missing information on definite integral solution 

message: It's my opinion that these lists of integrals would be significantly easier to read if the equality symbol for each formula was aligned in each row. I have created a short demo of how this would look (and appear in source) at User:Jounce/Integral list format.
Since this would be a large change I am merely leaving this here as a suggestion. Please comment if you agree or disagree with the change. Thank you. Jounce (talk) 19:25, 12 May 2017 (UTC)
