Jose, Works for me. The result Mathematica generated is Pi/( 3*sqrt(3) ). I am using Mathematica 4.0 for Windows. I am wondering if you perhaps used some special formating (formatting palette) that recast the integrand into a different form that cannot be solved analytically. Also, you can try NIntegrate[1/(2(1-x^2)^(1/2)+(1-x^2)),{x,0,1}] since you are evaluating your integral between two numerical limits.

Thx in advance.Regards Jose M Lasso PS:Sorry for my english
