Dear mathgroup, consider the following integral: sol=Integrate[ (4a (1-u^2)^(a-2)(s-u)s)^(-1/p), {u,0,s}, Assumptions-> {a>1,p>1,1>s>0,Element[s,Reals],Element[p,Rationals],Element[a,Rationals]} ] I do not know why i got complex result, which is in this case unexpected. does anyone have any idea? is this a bug or i overlooked anything?
