    VERY short tabular method
    From: Dave Walden
    Date: 2009 Sep 28, 19:01 -0700

    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!
