...of the compass. Q. How do you find the true amplitude ? A. As the co-sine of the latitude: is to the radius : : so is the sine of the sun or star's declination : to the sine of the true amplitude. Or if the secant of the latitude be added to the sine of the sun or star's declination, the sum (rejecting... | |

...setting, and from thence the variation of the magnetic needle, with an azimuth compass. As the co-sine of the latitude is to radius, so is the sine of the sun's declination at setting or rising to the sine of his amplitude from the W. or E. Next, calculate... | |
