Please write an answer with the code you came up with, and then the rest of us might be able to offer additional suggestions/comments on it. You can accept your own answer, too. | |

Either While[] or NestWhile[] might be useful.

| Jun 9, 2016 at 11:59 | comment | added | AnInquiringMind | @J.M. That's a good idea. Are there any built-in functions that can help with this, or will I need to implement this entirely manually? Thanks! | |

| Jun 8, 2016 at 22:01 | comment | added | AnInquiringMind | @ciao It's based on an entire notebook of calculations and function definitions, so it wouldn't be easy to post it. In any case, the essence of the question is captured by using a simpler function like $\sqrt{2-x}$ (maybe someone can come up with a good numerical example) instead, so I am hoping to save everyone from needless (and potentially distracting) details! | |
| Jun 8, 2016 at 21:57 | comment | added | ciao | Is there a reason the actual function can't be posted? | |
