Which method is the most effective to solve the indefinite integral \[ \int\sin(\ln x)\mathrm{d}x \] in the range \( (0;\infty) \)?
By parts integration, when we let \( u(x)=\sin⁡(\ln ⁡x) \), where \( u(x) \) is the integrated function, and we let \( v'(x)=1 \), where \( v'(x) \) is the differentiated function.
By substitution, \( a=\sin ⁡x \).
By parts integration, when we let \( u(x)=\ln x \), where \( u(x) \) is the integrated function, and we let \( v'(x)=\sin x \), where \( v'(x) \) is the differentiated function.
By substitution, \( t=\sin⁡(\ln⁡ x) \).
