Tell our children the importance of mathematics, in its applied form. All of the monuments that we have shown to you including the Great Pyramids, had to be architecturally drawn, mathematically calculated—using algebra, plane geometry, trigonometry, and engineering statistics. The same as today.
Little children, only rigorous engineering standards, precise planning, careful organization of labor and technical materials could finish such complex construction projects with such a high level of design quality. Nowhere outside of Africa exists such colossal structures built on such a precise and massive scale so early in ancient history. For example, Problem no. 56 in the Rhind Papyrus provides an equation to find the angle of the slope of a pyramid’s face. This is in fact its cotangent. With a cotangent, one automatically arrives at a tangent by taking the inverse of the cotangent. In addition, the pyramidal models sine and cosine values were available and known. Therefore, trigonometry was also developed earliest, very early, in the Nile Valley.
The advanced quality of this mathematics is confirmed by an architectural drawing even older than the Rhind Papyrus that shows that Nilotic engineers had learned to find the area under a curve more than 5,000 years ago.
Lies lose their power to mislead you when you already know in your heart the truth
