    • Abstract
  • In this paper the cosine transform matrix relating Cartesian coordinates with orthogonal curvilinear coordinates is introduced. It is shown that this transform matrix is an orthogonal matrix. Using the cosine transform matrix the Cartesian tensors, differential operators and related equations can be readily transformed into corresponding expressions in orthogonal curvilinear coordinates.
