Find the volume of the prism.
The basic formula for a prism is the area of the base times the height.
V = Bh
Since the base is a triangle, the first thing we gotta do is find the area of that triangle.
B = ½bh
B = ½(10 in)(7 in)
B = 35 in^2
Now, we plug that value into the volume formula.

Math Help
If $f(x) = e^{\cos x} \cos (\sin x)$ then $f(2\pi-x) = f(x)$. So the integral from 0 to $\pi$ is half the integral from 0 to $2\pi$. Next, f(x) is the real part of $e^{\cos x} (\cos (\sin x) + i\sin
(\sin x)) = e^{\cos x + i sin x} = e^{e^{ix}}$. Put $z = e^{ix}$.

Induced Subarrays of Latin Squares Without Repeated Symbols
We show that for any Latin square $L$ of order $2m$, we can partition the rows and columns of $L$ into pairs so that at most $(m+3)/2$ of the $2\times 2$ subarrays induced contain a repeated symbol.
We conjecture that any Latin square of order $2m$ (where $m\g... | {"url":"http://www.combinatorics.org/ojs/index.php/eljc/article/view/v20i1p44","timestamp":"2014-04-21T15:31:59Z","content_type":null,"content_length":"15330","record_id":"<urn:uuid:e0a04dcc-329c-4648-b879-a268828d4318>","cc-path":"CC-MAIN-2014-15/segments/1397609540626.47/warc/CC-MAIN-20140416005220-00556-ip-10-147-4-... |

About a improper integral
I would like to ask about this integral:
integral from 2 to infinity [ ln x /(exp(x) +1) ]
I think it diverges, but I don't know how to show it diveges.
first, I thought [ ln x /(exp(x) +1) ]can't be integrate,

Statistics and Probability
In case of a frequency distribution, the median is given by the formula
~ h n
X =l + −c f 2
Where l =lower class boundary of the median class (i.e. that class for which the cumulative frequency is just in excess of n/2). h=class interval size of the median class f =frequency of the median
