calculus - Evaluate the integral intfrac12+3sinx,textdx.

Please evaluate the integral,



12+3sinxdx.



What I have tried is to substitute sinx=1xx but I was stuck in a maze. Also, I did look a the wolfram solution. Can anyone propose a different solution from Wolfram, perhaps simpler with a bit of explanation?
