This object group only samples the devices relating to plane trigonometry in the Smithsonian collections. Separate object groups discuss spherical trigonometry, mathematical tables, sectors, slide ...

THIS is, in general, quite a well-written book, though, in some respects, on old lines. It covers elementary trigonometry to the logarithmic solution of triangles, and makes a good beginning by ...

TODHUNTER's “Trigonometry” is a very familiar friend of ours, and we have now before us a bundle of letters which we received from the author in 1861 and 1862, in reply to our criticisms and ...

Praxis the robot and Alan the “human man” attempt to land a plane using their knowledge of trigonometry. Luckily, the plane is full of ancient mathematicians who fill in some history of the ...

Trigonometry, as the Bohemian-born scholar Piticus named the discipline in 1595, also found a place in gunnery, in surveying, and in the physical sciences. From the seventeenth century, scales of ...
