trigonometry, which studies the measure of triangles, takes algebra to the next level its most well-known features include the pythagorean theorem and the sine, cosine, and tangent ratios. Trigonometry in the modern sense began with the greeks hipparchus (c 190-120 bce) was the first to construct a table of values for a trigonometric functionhe considered every triangle—planar or spherical—as being inscribed in a circle, so that each side becomes a chord (that is, a straight line that connects two points on a curve or surface, as shown by the inscribed triangle abc in.
