Recall that solving an equation of the form f (x) = means finding its roots. The root operation locates the real root to which Newton's method converges given an initial iteration point.

The root operation revolves around a single
loop (see Example 13-3), which
calculates successive approximations using the Newton iteration
formula. In the implementation presented here,
` f` is the function for which we are
approximating the root, and
