Trigonometry (called "trig" for short) (from Greek trigōnon "triangle" + metron "measure")is a branch of mathematics that deals with triangles, particularly those plane triangles in which one angle has 90 degrees (right triangles). Trigonometry deals with relationships between the sides and the angles of triangles and with the trigonometric functions, which describe those relationships... One of the earliest works on trigonometry by a European mathematician is ''De Triangulis'' by the 15th century German mathematician Regiomontanus. Trigonometry was still so little known in 16th century Europe that Nicolaus Copernicus devoted two chapters of ''De revolutionibus orbium coelestium'' to explaining its basic concepts.
