 b^^y, b<1 and y<-2 to evaluate to the real number!?? nuninho1980 Fellow Posts: 96 Threads: 6 Joined: Apr 2009   03/22/2010, 04:21 PM (This post was last modified: 03/22/2010, 04:22 PM by nuninho1980.) 0.5^^(-4.3)~=4.03335... woww! but... is this result correct!?? (http://en.wikipedia.org/wiki/Tetration - you look with attention to "Polynomial approximations" -> "Examples: (...)") if this number is correct then I ask if what is the better code of tetration (for mathematica, maple or other program math). bo198214 Administrator Posts: 1,395 Threads: 91 Joined: Aug 2007 03/23/2010, 10:59 AM (03/22/2010, 04:21 PM)nuninho1980 Wrote: 0.5^^(-4.3)~=4.03335... woww! but... is this result correct!??
