27. Substitute x=tanA we get tan^-1(3tanA-tanA^3)/(1-3tanA^2)=tan^-1(tan3A) as the above fraction is formula for tan3A. it is equal to 3A=3tan^-1x. on integrating we get as above 3xtan^-1x-3/2log(1+x^2)+c.

after that we get 3A .As A=tan^-1x then i integrating
started integrating tan^-1x.
that's all .
