Thanks a lot. Now it works indeed!

I'm afraid it's not correct. I've just tried what you said and it didn't worked either :confused:

Hi, when I run those commands in mathematica: y[x_,A_]:=Sin[x]+A+5 Plot[{y[x,5],y[x,6]},{x,0,5}] z[x_]:=D[y,x] Everything seems to go well. But when I trie to plot the derivative: Plot[{y[x,5],z[x]},{x,0,5}] I allways have these errors: Plot::plnrz[x] is not a machine-size real...
