In this volume I present some examples of Basic Concepts, Examination of Functions, Level Curves and Level Surfaces and Description of Curves, 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, . a short description of what is the problem. D Decision, . a reflection over what should be done with the problem. I Implementation, . where all the calculations are made. C Control, . a test of the result. This is an ideal form of a general procedure of solution. It.
