Trigonometrie: or, The doctrine of triangles
Subtitle: divided into two books. The first shewing the mensuration of right lined triangles: the second of spherical, with the grounds and demonstrations thereof. Both performed by that late and excellent invention of logarithms, after a more easie and compendious manner, than hath been formerly taught. Whereunto is annexed (chiefly for the use of seamen) a treatise of the application thereof, in the three principal kinds of sailing. With exact tables of the suns declination, newly calculated: and tables of the right ascension and declination of some eminent fixed stars, with the true times of the coming to the meridian at four of the clock in the morning, fitted for the present season, and may serve for many years without any alteration. Also other necessary tables used in navigation. By Richard Norwood, reader of the mathematicks
Edition: This seventh edition being diligently corrected, in divers difficult places explained; new tables of the stars right ascensions and declinations added, and the whole work very much enlarged, by the author himself
