    Question on Navigation: For Students or Mariners...
    From: David Cortes
    Date: 2012 Jan 5, 12:56 -0800

    First of all, let me say that I was greatly saddened to hear of Mr.
    Huxtable's passing. I hadn't kept up with this site for a long time, and
    when I came back a few weeks ago, his posts were the first I looked for.
    They were so lively, in that professorial way of his. I miss him, as I'm
    sure all of us do.

    I have a question for anyone who can answer it. (I suspect all of you can.)
    At pages 142-43 of a book titled, "Navigation: For Students or Mariners
    Preparing to Take Examinations etc.etc.," the author (George Leonard
    Hosmer) sets out two tables with calculations involving secant, cosecant,
    cosine, and sine. Unfortunately, he does not explain how these operations
    are used, and I, being a mere lawyer, not a mathematician, cannot interpret
    his tables, even with the help of the accompanying text. Can someone
    explain what he's saying, and how he's using these trig functions?

    The book can be found at:

    For here, go to pp. 142-43, and see accompanying text.
