Tables de Sinus Tangentes et Secantes
A 1683 French-language book of trigonometric sine, tangent and secant tables by François Schooten, illustrated with small geometric diagrams of triangles and circles that explain the angle and line relationships behind the tables. The pictures are plain black-line diagrams with capital lettering and dotted construction lines, offering a designer simple, legible schematic forms for technical or mathematical layouts.
