and seriously...
\[\int \frac{x}{2+\tan x}dx\]
that's integrable??? hahaha

If there would be 1 in the numerator then it can be integrated bu there is x..

I just lost my work. I can only think of by parts. I haven't tried any calculator, so I don't know if its integral is defined.

but wait for Ishaan sir
may be he would have a better way to solve

\[ \int \sin x /x dx\] is not integrable ... somehow this integration seems same type.
