Using Version 4
Integrate[1/(2(1 - x^2)^(1/2) + (1 - x^2)), {x, 0, 1}]
Pi/(3*Sqrt[3])
% // N
0.6045997880780727
If your version can't do the symbolic integral, try using numeric integration
NIntegrate[1/(2(1 - x^2)^(1/2) + (1 - x^2)), {x, 0, 1}]
0.6045997895732339
NIntegrate[1/(2(1 - x^2)^(1/2) + (1 - x^2)), {x, 0, 1 - 10^(-15)}]
0.6045997619134842
