Use classic (X1-X0)/X0 to explain the solution.

Another take on the good-enough? function

Explain more of the rationale for the alternative

Gave an example on the large numbers and the problems I encountered with the old algorithm.

Removed superfluous arg 'x' for radicand (new strategy doesn't need it)
112013-05-03 23:43:17+1 -0 line(s)[View this version, source] [Diff to current|previous]
Added question comment about why x was an arg in good-enough? when it's not even used.

The explanation for why the good-enough? test is not very good for large numbers was not quite right in stating that the algorithm did not terminate in this case.

Added an alternate version I used for the solution. This is also found in other places such as: http://http://wiki.drewhess.com/wiki/SICP_exercise_1.07 --Coldsalmon

Removed extra abs, not needed. This algorithm can't handle negatives regardless.

trim to display only the best solution

Corrected the first solution.
