Hello, Well in my calculus class, I need to integrate the following expression: (x^3/(x^4+x^2+1))dx, I solve the integral with Mathematica, but a few classmates got a different answer using other symbolic algebra system, the answers are totally different, the answer that my classmates got is: 1/4 Ln(x^4+x^2+1)-(Sqrt(3)/6) ArcTg((2x^2+1)/Sqrt(3)) is this the correct answer?? Thx in advance. Regards Jose M Lasso
