Trigonometrie. Or, The doctrine of triangles divided into two bookes: 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, than hath beene formerly taught. Whereunto is annexed (chiefly for the use of seamen,) a treatise of the application thereof in the three principall kindes of sailing. With certaine necessary tables used in navigation.
