Ti-86 i have been using for years and its awesome. The conversion algorhythm comes in quite handy for units. Also, Poly function is handy for quick quadratic equations. Anthing that the Ti-89 has over the 86, id rather use Maple or Matlab since these programs handle vector/multivariable calculus better and with a nicer image.
oh, this reminds me, i've got an 89 someone gave me that has a broken screen, but i don't have anything to get the back off, could i get a new screen and replace it after i get something to get the back off? when you turn it on, you can see part of the menu, but theres a crack in the screen so not much is visible, so i know it works, but its jsut the screen
Well since the 89's do symbolic integration, it makes sense that they would be banned in a calculus class. I have the 86 cuz it was the same calculator my calculus teacher used. So she would teach our class alot of quick shortcuts and stuff on how ot use the caluclator.
Ti-86 is a great calulator... definitely better than an 83 or 83-plus. I haven't used the new 84, so I can't comment on that. However, I much prefer the "higher rez" screen of the 86. Which reminds me... I have an old 86 that I need to sell. Once you go 89, you never go back
ti89s are AWESOME for calc. you can do anything imaginable. yes, you better make sure your instructor allows it. because itll become a crutch when you do integrals/differentials/limits/etc.
