We cannot know where the input came from and have to take it one step at a time. SIN(3.14159265359) = SIN(PIx) = SIN(x) ~= x for small x, and that is the only correct result, x = 2.06761537357e13, incidentally correct to 12 digits, a feat as yet unmatched in TI calculators (correct me if I'm wrong) It is not because ASIN(x) produces 3.14159265359 for a myriad numbers that they would all be the correct result for SIN(3.14159265359)? Would you like your 12digit calculator to return 1e250 for SQRT(0)? Cheers, Werner 41CVâ€ ,42S,48GX,49G,DM42,DM41X,17BII,15CE,DM15L,12C,16CE
