are you miss spelled something ? cuz integral xlogx /(1+x^2)^2 is quite easy for solve... but log(x) ??? not so easy. only log(x) you...
i solve that manually i only wanna see is there other way to get same solution.. as alpha said 'solution step by step' and when you click to see it it's said 'solution step by step don't exist'
Thanks mr. Frank Kampas... ;)
