Question

I have a question of how to solve an integral I'll post it in a reply

Answer 1

\[\int\limits_{}^{}dx \div x \times \sin (\ln (x))\]

Answer 2

put ln x = u

Answer 3

1/x dx = du

Answer 4

thnx now I see how

Answer 5

Can you solve it now ?

Answer 6

something else now I have \[\int\limits_{}^{} dx \div \sin ( \ln(u) ) \] how do I solve that?

Answer 7

instead of dx is du

Answer 8

you have some confusion. It becomes
\[\int\limits {\frac{du}{\sin u}}\]

Answer 9

oh yes you're right :)
