IntroductionWe construct four iterative methods for solving an equation
f(x) = 0. They are: Newton's method, in which we go from the
old point to the new by finding where the linear approximation
to f at the old is zero; poor man's Newton which is the same
except we approximate the slope in the linear approximation,
and two interpolative methods. Topics13.0 Solving an Equation in One Variable 13.1 Newton's Method 13.2 Poor Man's Newton 13.4 Divide and Conquer
