Explain-variation of newton method


Explain the steps on how to solve the problem below:

A)  Consider a variation of Newton’s method in which only one derivative is needed; that is  xn+1=xn-f(xn)/f′(x0).Find C and s such that en+1=Cesn.

B)  Find the conditions on α to ensure that the iteration xn+1=xn-af(xn)  will converge linearly (en+1≈ 1/2 en) to a zero of f if started near the zero.
