Print[ FullSimplify[ArcCos[(Sqrt[3]-1)/(2*Sqrt[2])]]//InputForm];
Print[ FullSimplify[ArcSin[(Sqrt[2]+Sqrt[6])/4]]//InputForm];

(5*Pi)/12

ArcSin[(Sqrt[2] + Sqrt[6])/4]


Both answers should be 5*Pi/12.  This is fouling up a script.
Is there a way to get FullSimplify to do exactly that for
the ArcSin?
