Показать описание
Trigonometry (from Greek trigōn, "triangle" and metron, "measure") is a branch of mathematics studies relationships between side lengths and angles of triangles. The field emerged in the Hellenistic world during the 3rd century BC from applications of geometry to astronomical calculations. The Greeks focused on the calculation of chords, while mathematicians in India created the earliest-known tables of values for trigonometric ratios (also called trigonometric functions) such as sine
In this video, Sin(x+y) =Sinx Cosx +Cosx Siny, Sin(x-y)=Sinx Cos y + Cos x Sinx are discussed.
