2 Prepare TVLs for conjunctions dx3 dx4, dx3 dx4, dx3 dx4, and dx3 dx4, as objects number 30, . . . , 33, and VTs of x3, x4, and x3, x4 as objects number 34, 35, and 36.

Vectorial Differential Operations). Calculate all vectorial derivative operations based on the partial differential operations of Exercise 4.6 and verify the results. Build the three differential operations of Exercise 4.6 using the vectorial derivative operations of XBOOLE and verify the results. Use function (4.2) for all calculations.
