Sir, I had posted the following question on 21st March and you have solved it. ?(x^2 ?tan?^(-1) x)/(1+x^2 ) dx Even after putting the value of t, the answer does not agree with the answer given in the book. The answer given in the book is: x?tan?^(-1) x-1/2 log(1+x^2 )-1/2 (?tan?^(-1) x)^2+C.So, please confirm the correctness of the answer.
