Using Newton's Iterative method to find the root of the following equation near 1.5:2x^3-4x^2+3x-6=0
As for the Newton iterative method, in the course of computational methods, the basic formula is:
xn+1=xn-f (Xn)/F *(Xn) xn+1 is the n+1 iteration result,Xn is the nth iteration result,f * ( Xn) is the Guide function value of f (Xn) .
Basic steps:
The first step

1. In JavaScript, the arguments object is a more specific object, which is actually a built-in property of the current function. Arguments is very similar to an array, but is not actually an array instance. Can be confirmed by the following code (of course, in the function Funcarg, the call arguments is not necessarily written funcarg.arguments, write arguments directly).1 ARRAY.PROTOTYPE.TESTARG = "Test"; 2 function Funcarg () {
