    Millard Kirk and Dan Hogan have suggested the simplfied formulae for
    calculating MPs. The formulae is sufficeintly accurate for praticle use.
    If you are looking for the same accurracy as that published in the
    nautical tables, especially for use in high latitudes, you will need to
    use a more complicate formulae. I have writen an JavaScript program to
    calculate MP and some other navigation calculations which are available
    from my web page at http://www.geocities.com/CapeCanaveral/2265 . By
    viewing the source, you can reduce back the formulae.
