Basis vectors in three-dimensional space

Description

\loadmathjax

Objects ex, ey and ez are the three elementary one-forms on three-dimensional space, sometimes denoted \mjseqn(e_x,e_y,e_z). These objects can be generated by running script ‘vignettes/ex.Rmd’, which includes some further discussion and technical documentation and creates file ‘exeyez.rda’ which resides in the data/ directory.

Details

See vignettes dx and exeyez for an extended discussion; a use-case is given in vector_cross_product.
