The trigonometric ratios didn't get their current European names until the 12th century or so. The ratios' current names come to us as a result of those Middle-Ages Europeans making some mistakes when they translated Arabic texts. The history of trigonometry is rather tangled. [source]...
THE interpretation of formulas in the trigonometry of plane and spherical triangles is greatly simplified by the expedient of designating the sides by the same letters, respectively, as the angles opposite those sides-one group of letters being capitals, A, B, C, and the other group small ...

In hisMetrica, Hero provides four procedures for finding the area of a circular segment (withbthe base of the segment andhits height): an Ancient method for when the segment is smaller than a semicircle,; a Revision,; a quasi-Archimedean method (said to be inspired by the quadrature of ...
Using Trigonometry to Find Lengths – A Simplified Guide To use trigonometry to find lengths, I first identify the specific functions related to the sides of a right-angled triangle: sine, cosine, and tangent. These trigonometric ratios compare the lengths of two sides of the triangle, depending...
