英语词汇“newton's method”的英英意思、用法、释义、翻译、读音、例句、短语、词组-英语词典

1. Mathematics. Used attributively and in the genitive with reference to various methods of numerical analysis developed by Newton or based on his work, esp. methods for approximating the solution of an equation and for approximating the integral of a function; as Newton formula (also Newton's formula) (see also sense 2d), Newton process (usually with reference to the Newton–Raphson method), Newton's method, Newton's rule. Cf. Newton–Cotes n., Newton–Raphson n.Newton's method of approximating the solution of an equation involved the same reasoning as the Newton–Raphson method, but was procedurally different.Newton's method of approximating the integral of a function over a finite range involved evaluating the function at each of a series of arguments in the range, and finding a polynomial function with the same value at each of the arguments.
