    Try arcsin(). My spreadsheet is very similar to Excel,
    but it is not exactly Excel.

    You mean there is a movie?
    I just read the book (under the influence of some recent
    Nav-l discussions) and I liked it very much.
    Our library also has "Hornblower Companion", with all maps
    and technical commentaries to all Hornblower's travels and battles.
    Very exciting:-) I regrett I missed this in my youth,
    but in my youth I could only read those books which have been translated
    into Russian, and Hornblower was not.
