;- "All men by nature‚ desire to know."l tllroughtout history the need to know has been a prime source of I governing mens actions. This need has founded civilizations‚ it has started wars‚ and it has led man to his ultimate control of his environment 1 I shall examine the causes and developments of mathematics. Starting with early Egypt and Babylon‚ then on to classical Greece‚ and finally the 17th century through modern times; I will trace the need and development of mathematics. "Priority

volume. The concept used to solve the problem To calculate the volume of the cube‚ length x breadth x height was utilized. This gave a cubic equation. This equation was then differentiated which gave a quadratic formula. dydx was then equated = 0. The quadratic was then solved using the quadratic formula ( x=-b±b2-4ac2a) to obtain two values of (x). These values were then substituted into the second differential (d2ydx2). If the value substituted produced a negative value‚ then that will be the
