WebUnlike the bisection and false position methods, the Newton-Raphson (N-R) technique requires only one inital value x0, which we will refer to as the initial guess for the root. To see how the N-R method works, we can rewrite the function f ( x) using a Taylor series expansion in ( x - x0 ):

WebDec 27, 2024 · You can use any value as the initial guess for the Babylonian method of calculating a square root (other than 0), but the closer the guess to the root, the more accurate your result per iteration. Of course you cannot expect to use the correct root as the initial guess, otherwise you've already solved the problem.
