 Author Comment/Response yehuda ben-shimol 09/26/10 02:47am D[Sin[x]^2] returns the desired result if you would like to use Derivative formalism then you need to define a function that is Derivative[1][Sin[#]^2&][x] Since you didn't quoted your code, I suspect problems might be with 1) use Capitals for built in functions, e.g., Sin rather than sin 2) use Square brackets for function arguments, that is, Sin[x] rather than Sin(x) (or sin(x)) which denotes multiplication in Mathematica 3) defining the variable for the derivative (therefore use D[...,x] or Derivative as I used above) yehuda URL: ,
