[QUOTE]Originally posted by zarahan- aka Enrique Cardova: [QB] Some of the info above is not quite accurate. Are you sure about the following below for example? WHat's your source? [b]" And when as Muslims they needed to accurately determine the location of Timbuktu and Mecca, they surpassed the Greeks by inventing the functions of trigonometry." [/b] ^^Questionable. The Egyptians can be said to have developed or at least pioneered trig based on their need for building pyramids, temples, and other structures. It is unclear how Muslims invented trig. The Egyptians had it going on long before Muslims appeared. QUOTE: [i]"The Rhind Papyrus, and Egyptian collection of 84 problems in arithmetic, algebra and geometry dating from about 1800 BCE, contains five problems dealing with the seked. A close analysis of the text, with its accompanying figures, reveals that this word means the slope of an incline- essential knowledge for huge construction projects such as the pyramids... This [example] is actually the "run-to-rise" ratio of the pyramid in question- in effect, the cotangent of the angle between the base and the face. It shows that the Egyptians had at least some knowledge of the numerical relations in a triangle, a kind of "proto-trigonometry." [/i] --Britannica Educational Publishing (2010).
