    Re: Logarithms: adding ten

    Instead of adding 10 to a negative log just try multiplying the secant and cosecant by 100,000 as is done in the Ageton tables. Makes celestial navigation life much easier. Now then put the natural sin and cos next to the log secant and cosecant x100,000 and you have a very handy table. See attached table in the style of Hewitt Schlereth.
