I have two related question. Let me introduce a pure function f = #1^2 + #2 & Now. I want to make an operation over the function, for example to find its square and to call the result (the expected function f = (#1^2 + #2)^2 & ) c: c=f^2 However, I do not obtain this, as c[a,b] does not evaluate to (a+b)^2. Can anybody advise me how to obtain such a function without long substitutions. I would like to obtain something which is made for derivatives : In[11]:= Derivative[1][f] Out[11]= 2 #1& In[12]:= Derivative[2][f] Out[12]= 2& Regards Vlad
