Hello, The term Cosh[43Pi/Sqrt] has the value 1.5263010243767756 x 10^41, and the rest of the expression has a nearly equal but opposite value - so evaluated to machine precision the subtraction leaves just noise. If you apply FullSimplify it simplifies your expression to something that has only one term - so that presumably yields the correct answer. David Bailey http://www.dbaileyconsultancy.co.uk
