In this volume I present some examples of napla calculus, vector potentials, Green’s identities, curvilinear
coordinates , Electromagnetism and various other types, cf. also Calculus 2b, Functions of Several
Variables. Since my aim also has been to demonstrate some solution strategy I have as far as possible
structured the examples according to the following form
A Awareness, i.e. a short description of what is the problem.
D Decision, i.e. a reflection over what should be done with the problem.
I Implementation, i.e. where all the calculations are made.
C Control, i.e.
