Razão e definição. A ideia dos logaritmos é reverter a operação de exponenciação, isto é, elevar um número a uma potência. [14] A título de exemplo, a potência de três (ou o cubo) de 2 é 8, porque 8 é o produto dos três fatores de 2: [15] = = Disso resulta que o logaritmo de 8 na base 2 é 3, ou seja: [16] log 2 8 = 3. Exponenciação. A potência de três de qualquer número ...

A difference engine is an automatic mechanical calculator designed to tabulate polynomial functions.It was designed in the 1820s, and was first created by Charles Babbage.The name, the difference engine, is derived from the method of divided differences, a way to interpolate or tabulate functions by using a small set of polynomial co-efficients. Some of the most common …

Initial estimate. Many iterative square root algorithms require an initial seed value.The seed must be a non-zero positive number; it should be between 1 and , the number whose square root is desired, because the square root must be in that range.If the seed is far away from the root, the algorithm will require more iterations.
