Help me out sci, im studying for a Calc 3 test i have on friday and im having trouble with a problem from the textbook (pic related)
Find the Value of the triple integral;
[math]\iiint\limits_E \,xy \mathrf{d} V\ [/math]
(my latex may suck, its the triple integral of (xy)dV on the region E). Where E is the pholyedron with vertex (0,0,0) (1,0,0) (0,2,0) and (0,0,3).
The problem im having is that the solution on the textbook is (8/3e). i really dont know how you could end up with e on the result.
thank for your help guys.

latex didnt went so bad, just ignore the red part.

oh and btw, what i did was the iterated integral where:
0<x<1
0<y<2-2x
0<z<3-(3y/2)-3x
[math]\sum_{n=0}^\infty \frac 1 {n!} = e[/math]
Hi /sci/, I need some help with choosing a sorting algorithm for a website I'm coding. /g/wdg/ is useless and keeps calling me an autist when I point out that their suggestions are not even related to what I was asking for (for example, one poo in the loo linked me to a tutorial on how to sort an array numerically, which isn't what I was asking for at all).
So here's what I need:
I want to take in how old a given post on my website is and what rating it has, and then output a natural number which ranks the said post. The higher the rank, the higher in...

Hot damn CS tards are stupid.

I'm simply looking for a suggestion. I could easily write any function of that sort, but I'm looking for an optimal one.

>sorting shit yourself
This is what you do. In your database at a column called 'Rating'.
Then, make an algorithm that by using the date of the post and the likes or whatever it has produces the natural number that ranks the post.
Then, everytime someone likes a post have it run that algorithm to recalculate immediately.
Then, when someone looks up your website simply do this:
SELECT * FROM Posts ORDER BY Rating ASC

Is this still a good read?
That hasn't become dated by new scientific developments?
I want to have it on my coffee table so I can come off as a pretentious atheist to my girlfriends culturally catholic parents.
It's definitely a worthy read, especially if you have an interest in evolutionary biology.
While dated and erroneous in some aspects, Darwin's insight was impressive for the time and he presented his arguments very well.

Yes, though a bit outdated. If you are a popscientist and have an interest in evolutionary biology I would recommend Richard Dawkins. His grasp on evolution is unparalleled and his writing is lucid and crisp. I recommend The Ancestor's Tale. Do stay away from his anti-religios books, if you are not into that sort of thing. He can be a bit zealous

What's the current view on evolution? I've heard that some scientist are moving away from the standard theory.
Is it true or just creationismfags in denial?
