Trigonometrie, or, The doctrine of triangles divided into two books: the first shewing the mensuration of right lined triangles, the second of sphericall, with the grounds and demonstrations thereof. Both performed by that late and excellent invention of logarithmes, after a more easie and compendious manner, then [sic] hath been formerly taught. Whereunto is annexed (chiefly for the use of seamen) a treatise of the application thereof in the three principal kindes 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 their coming to the meridian, at 4, 12, and 8 of the clock: 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.
