The trissotetras: or, a most exquisite table for resolving all manner of triangles, whether plaine or sphericall, rectangular or obliquangular, with greater facility, then ever hitherto hath been practised: most necessary for all such as would attaine to the exact knowledge of fortification, dyaling, navigation, surveying, architecture, the art of shadowing, taking of heights, and distances, the use of both the globes, perspective, the skill of making the maps, the theory of the planets, the calculating of their motions, and of all other astronomicall computations whatsoever. Now lately invented, and perfected, explained, commented on, and, with all possible brevity, and perspicuity, in the hiddest, and most re-searched mysteries, from the very first grounds of the science it selfe, proved, and convincingly demonstrated. By Sir Thomas Urquhart of Cromartie Knight. Published for the benefit of those that are mathematically affected.
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, afte 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 sayling. 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 o the mathematicks.
