Re: prolate / oblate spheroidal coordinates



 The following are what I found in Arfken (3rd Ed) page 117:
 Morse, PM and Feshbach, H, "Methods of THeoretical Physics", NY:McGraw
 Hill
 (1953).  Chapter 5 inlcudes a description of several different coordinate s
 systems.  Note carefully that M&F are not above using left-handed coor-
 dinate systems even for cartesian coordinates.  ...  11 additional fascinating
 but seldom encountered orthogonal coordinate systems are discussed in the
 second (1970) edition of the above book.
