Apply Newton's method to the function f(x) = √x when x ≧ 0, f(x) = √(-x) when x ＜ 0, starting with the initial guess x = a ＞ 0. Calculate x and x . What happens? (Make a skech) 0 1 2 If you ever odserved this behaviour when you were using Newton's method to find a root of an equation, what would you do next. 我自己尝试做了一下~~ 做法如下~~ http://w1.loxa.com.tw/ahong/knowledge/ccu88-4.doc 可以请强者看一下哪边有问题吗!? 因为我觉得我是把答案给凑出来的... ※ 编辑: ahongyeh 来自: 219.68.186.165 (06/20 15:23)
