After reading this section of number theory, I think this algorithm is too incisive. In fact, it is really great to extend the Euclidean Algorithm to translate the formula in the book into code. I am still struggling with it like sb, in fact, I have already figured it out. However, the second method in the book to solve the binary one-time indefinite equation is still in struggle... Using the inference in the theorem, we can conclude that there must b

Obtain a solid root of the high equation 2x ^ 4-4x ^ 3 + 6x ^ 2-8x-8 = 0 (accuracy requirement: 10 ^-3) Algorithm analysis is as follows: There are many real-root algorithms for High-Level equations. Here we introduce a kind of bipartite method. If the higher-order equation f (x) is set to 0, a real root algorithm is obtained using the bipartite method as follows: 1. input the initial values X1 and X2 and c

Gauss's Law (Gauss's Laws): electric fieldThe electric charge (electic charges) produces a static electric field (static electric field). The electrostatic field line starts at a positive charge and points to a negative charge. The total amount of charge in any area is proportional to the second-type area of the corresponding electric field on the surface of the area. Represented by a formula is $$\int_{\omega} \FRAC{\RHO

The secant METHODIn numerical analysis, the secant method was a root-finding algorithm that uses a succession of roots of secant lines to be tter approximate a root of a function f. The secant method can be thought of as a finite difference approximation of Newton ' s method. However, the method was developed independently of Newton's method, and predated the latter by over 3,000 years.1 /*2 * =====================================================================================3 *4 * Filename:
