Dear Jakub, this is due to In[3]:= Attributes[Plot] Out[3]= {HoldAll, Protected} You must force Mathematica to evaluate the first parameter of Plot before Plot goes on processing. The easiest way to accomplish this is an explicit "Evaluate": Plot[Evaluate[D[x^3 - 6 (x + 1) 2 + x - 7, x]], {x, -3, 8}] Hope this helps, ciao, WW.
