Al-Biruni wrote over 100 treatises on astronomy, science, mathematics, geography, history, geodesy and philosophy. Only about twenty of these works now survive, and only about a dozen of these have been published.  Al-Biruni's treatise entitled Maqalid 'ilm al-hay'a (Keys to the Science of Astronomy) ran to over one thousand pages and contained extensive developments in on trigonometry. Among many theorems, he produced a demonstration of the tangent formula, shown below.
