How do I get Wolfram to render X with a subscript n, like that found in Halley's method for square root? I'm having a go with a new square root algorithm, and need to express iteration. See pic attached.
I'm not sure I understand your follow-up. I mean Wolfram|Alpha isn't for programming really. You kinda try things and if they work, then they work. Are you looking to use Subscripted variables with it or have it output formatted math formula? My advice is to just try it.
Thanks Sean. Will this also work on Wolfram Alpha Pro website?
