In this volume I present some examples of tangents to curves, tangent planes to surfaces, elementary integrals and Extrema, 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
