    [NavList 9978] VERY short tabular method
    From: Dave Walden
    Date: 28 Sep 2009 19:01

    While looking through:

    Practical tables for navigators and aviators, by Armistead Rust
    1918 - 116 pages

    I came upon his TABLE A--Log Secants and Cosecants. (One of several tables
    used in a reducion method he describes.)
    It is one page! Copy attached.

    Combining this with the Sec/Cosec method (see for example, Precomp
    Navigation, by Philip Van Horn Weems, 1969 - 18 pages), one has perhaps THE
    shortest tabular method, ONE page!
