=-\frac{\pi}{2}\ln (2) $ then we get $ \int_{0}^{\frac{\pi}{2}} \LN^{2} (\sin x) dx $ from the equation.Solution Four:Here is a completely different-approach this integral, which relies on some elementary complexanalysis (
cauchy ' s theorem). It is based in an approach which I had seen several times employed to compute $\int_0^{\pi/2}\log{(\sin{x})}\,dx$ (partic Ularly, in Ahlfors's book).
The idea was to integrate the principal branch of $f (z): = \log^2{(1-e^{2iz})} = \log^2{( -2ie

the variable i as an integral type, occupies 4 bytes of memory space, and the initial value is 10. Roughly speaking, this statement in the execution of the operating system from memory allocated 4 bytes (if the address is 0x00000000-0x00000003), put these 4 bytes a label, called I (without the label, want to read and write these 4 bytes can only use binary or hexadecimal address, more trouble). Then, if the program reads and writes I, it represents the 4 bytes of reading and writing. So I is a

This indicates that this statement is correct and the problem occurs during the stored procedure. I am using a DBA account to log on to the system.

2) Lucene's filtering and sorting process can meet 90% of the requirements. Filtering can delete unnecessary results, while sorting can sort the results based on the values of a certain field. Basic vertical search engines require these functions, because these functions can reduce the query result set and improve the user experience. Baidu and other commercial search engines obviously do not need (or are not provided) these features.
3) Lucene's score calculation results are good. Aside fr

I chose Google Code as the platform, but Google Code does not use TFS, that is, it cannot use team explorer. Then we can see a help article on Google Code.ArticleIntroduction to ankhsvn, which c
