    QUOTE

    Captain Lane was famous for saying that all the math classes he took after high school never did him a bit of good, and spherical trigonometry was of no value in understanding celestial navigation (!).

    UNQUOTE


    "in UNDERSTANDING Celnav ..." : not really necessary, I buy that one.

    "and in computing then ???" : maybe spherical trigonometry might be useful - oh !!! just a bit, only - now and then, no ???
