...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...
