Hi I work with Maple 9 and I came across to this problem. I don't know where the problem is. >restart: > simplify(convert(sin(1/2*Pi*(-I*x+5)),exp)); > simplify(convert(cosh(1/2*Pi*x),exp)); does it mean that: >sin(1/2*Pi*(-I*x+5))=cosh(1/2*Pi*x); for all x's? Now look at this paradox: >x:=100; > evalf(sin(1/2*Pi*(-I*x+5))); > evalf(cosh(1/2*Pi*x)); where is the problem? cheers Sayed
