Well, Hugo, we still don't know what integral you want because sqrt is not a
Mathematica function and there is a missing bracket. But assuming the
following we easily obtain an answer in Mathematica Version 7.0.1.

answer = Integrate[Sqrt[t*(1 - z)*(t - z)], {t, 0, z}, 
  Assumptions -> z > 0] 

1/8 \[Pi] Sqrt[-1 + z] z^2

Could any body help me to solve the following integral in
mathematica?

Integrate[sqrt[t * (1-z)*(t-z),{t,0,z}];  t and z are reals; z>0

I did make a mistake posting the wrong equation yesterday, I apologize
for that.

Any help would be appreciate,

Hugo
