TI-84+ OS 2.30 Distinguishes Asymptopes | Andy |
(Broken images removed, the alt text was: y=tan(x) y=1/cos(x) y=(1/((x-1)(x-2))) ) Apparantly TI isn't very good about making changelogs, because they never told us anything about the new goodies in TI-OS 2.30 for the 84+. According to these threads on the Detached Solutions forum, while OS 2.30 graphs functions considerably slower than OS 2.22, or other 8x calculators for that matter, it DOES check the graphs to see if there are any discontinuities, and shows them properly. This means, for example, that y1=1/(x-1) will NOT connect both parts of the graph! Even y2=1000rand-500 doesn't connect the dots, apparantly. If you want more yummy details, I suggest you read both threads. Many thanks to the newbies with legitimate questions (that were worded nicely...) wondering what was up. Their separate questions, when put together, made it click for Benjamin Moody (aka FloppusMaximus). No word yet on whether there's any way to turn this off to get faster graphing, but apparantly it only works for function graphing with lines. You can try animated line+ball graphing or parametric graphing to get rid of the checks and have it go faster.
Update 15 October 2005 23:00-ish by Andy: Added screenshot. Also, apparantly AMS 3.10 for the 89 Titanium and Voyage 200 also support this, and have an option to turn it off. Note that I'm just relaying what I think was said in a comment on this news article. Maybe I should go update my 89Ti to 3.10...
Update 18 October 2005 18:30-ish by Andy: Ok, so changing the graph style doesn't help -- you have to use parametric mode. You could also try using Xres=2, but that gives you generally fugly graphs anyway. Also added better screenshots. |
