Overview • Sections 10.6-10.10 • 10.6 Scalar and vector fields • scalar or vector that varies in space • 10.7 Vector operators • gradient, divergence, curl • 10.8 Vector operator formulae • learn the magic! • 10.9 Vector operators in polar coordinates • explains what was used before • 10.10 General curvilinear coordinates • generalizes e.g. polars; Einsteins theory of general rel.
Black board & Maple illustrations • Integral definitions of grad, div, and curl • Preview of Eqs. (11.14-11.16) page 404! • Preview of what line, surface, and volume integrals mean! • Beautiful; independent of coordinate systems! • Check that it means the same in Cartesian • Derive now easily the expressions in curvi-linear • Table 10.4, page 375b • Geometric interpretation • Visual / conceptual understanding!!!
Enough for today! Good luck with the Exercises!
