In[1]:= ?Derivative f' represents the derivative of a function f of one argument. Derivative[n1, n2, ..][f] is the general form, representing a function obtained from f by differentiating n1 times with respect to the first argument, n2 times with respect to the second argument, and so on. A one-argument function. Take first derivative and evaluate at x=2.2. In[2]:= f[x_]:= Sin[x]/x In[3]:= f'[2.2] Out[3]= -0.434545 A two-argument function. Take first derivative with respect to the second argument then evaluate at {3, 2.7}. In[4]:= Derivative[0,1][BesselJ][3,2.7] Out[4]= 0.187289 URL: ,
