...having any constant (c.) Similar tables have been computed by JA Ockereon and Jared Teeple, of the US Lake Survey. Their use is, however, limited, from the fact that the meter is the unit of horizontal measurement while the elevations are in feet. The bulk of the tables furnish differences of level for... | |

As c varies with different instruments these last two expressions were calculated for three different values of c, thus furnishing a ratio from which values of c sin n and c cos n can be easily determined for an instrument having any constant (c). Similar...
