its integration has unelementary function:

integrate ln(sinx) / sin(x) - Wolfram|Alpha

Do you post all informations of your problem? - Jan 10th 2010, 11:04 AMparkhid
yes. this links has solved the integral by semi numbers.

any other ideas ? - Jan 10th 2010, 12:11 PMmr fantastic

The derivative of $\displaystyle ln(sin(x))=\frac{1}{tan(x)}$

$\displaystyle \int\frac{ln(sin(x))}{sin(x)}dx$

An indefinite form for this is hard to come by. Parts, substitution, etc will not work too well. - Jan 11th 2010, 12:44 AMparkhid
