Given the initial value and allowable error, the preparation of Newton method to solve the equation f (x) 0 general procedure.
(2) Given the equation, it is easy to know that it has three roots
A) The local convergence of the Newton method is known to exist. At that time, the Newton iteration sequence converges to the root x2*. Try to determine as large as possible.
B) Try some initial values to observe the convergence of the Newton sequence and the root of the convergence.
(3) Through this on the machine, you understand what?
