  A generalized covariant method of analysis applicable to frames for which
time is not orthogonal to space, such as spacetime around a star possessing
angular momentum or on a rotating disk, is presented. Important aspects of such
an analysis are shown to include i) use of the physically relevant
contravariant or covariant component form for a given vector/tensor, ii)
conversion of physical (measured) components to generalized coordinate
components prior to tensor analysis, iii) use of generalized covariant
constitutive equations during tensor analysis, and iv) conversion of coordinate
components back to physical components after tensor analysis. The method is
then applied to electrodynamics in a rotating frame, and shown to predict the
results of the Wilson/Wilson and Roentgen/Eichenwald experiments.
