First edition of the last work published in Oughtred’s lifetime, in which he sought to establish a symbolic trigonometry.

William Oughtred (1575-1660) was one of the most influential English mathematicians of the seventeenth century. He was the teacher of John Wallis, and inventor of the circular and rectilinear slide rules.

“In 1657 Oughtred published Trigonometria... dealing with both plane and spherical triangles. Oughtred made free use of the abbreviations s for sine, t for tangent, se for secant, sco for sine of the complement (or cosine), tco for cotangent, and seco for cosecant. The work also contains tables of sines, tangents, and secants to seven decimal places as well as tables of logarithms, also to seven places’ (DSB). The tables were set by the printer and globe maker Joseph Moxon, famous for his Mechanick Exercises: or, the doctrine of handy-works, applied to the art of printing, 1683.
