Blatant editorializing
DVdm, what specific statement have I made that you consider blatant editorializing?  I really have no idea what I did that could be considered blatant editorializing.  I said, ""The reader should note the equations to be solved are not the equations for a hyperboloid discussed above:"".  Do you consider this statement to be blatant editorializing?  Now the reason I said this is because the discussion of hyperbolas and hyperboloids could easily mislead the reader.    "
