I don't know why when i'm googling solution for integral of ln|sin x|, the output i clicked always give me the solution integral of log(sin x) but the title is integral of ln|sin x|. Is integral of ln|sin x| equal to integral of log(sin x)?

When i asked the solution to my teacher whom gives that problem, he also confused and make me more confused. He tried many times and always failed.

So, does anyone here know the solution integral of ln|sin x|? Please help me, i am so curious about the answer.

The indefinite integral of ln lsin xl cannot be expressed in terms of elementary functions. If you have used Wolfram Alpha, you will see that it uses the special function Li(x), so we can't expect that the integral of ln lsin xl can be expressed in terms of functions we usually encounter like ln x, sin x, cos x, and many others.

but how?

hey I agree that this integral is very challenging. Firstly, ln|sinx| does not equal log|sinx| nor do their integrals. Secondly, is this a indefinite or definite integral, if so does it have any boundaries?
