I misplaced the e-mail but I think you asked about this:
expr=1/Sqrt[Sin[u]];
(int1=Integrate[expr,{u,0,Pi/2}])//InputForm
2*EllipticF[Pi/4, 2]
N[int1,15]//Chop//N//InputForm
2.6220575542921196
(int2=Integrate[expr//TrigToExp,{u,0,Pi/2}])//InputForm
(2*Sqrt[Pi]*Gamma[5/4])/Gamma[3/4]
int2//N//InputForm
2.62205755429212
