Dpart

Function: dpart (<expr>, <n_1>, ..., <n_k>) Selects the same subexpression as part, but instead of just returning that subexpression as its value, it returns the whole expression with the selected subexpression displayed inside a box. The box is actually part of the expression.

title(exp):=disp(dpart(exp));
(title("a classical textbook example of differentiation"));
x^x^x;
diff(%,x);

          (%i1) dpart (x+y/z^2, 1, 2, 1);
                                       y
          (%o1)                       ---- + x
                                         2
                                      """
                                      "z"
                                      """

(%o1)                                true
(%i2)
