Digital Cameras Photo Reviews of Texas Instruments(R) TI-89 Graphing Calculator
Customer Review: Simple, powerfull
Summary: 4 Stars
The only thing that I've never liked is that the letters in the screen are way too little, it takes time to get used to it(specially if you are a ti86 or hp's calcs former user), when compared to the newer hp models (50g and so on..) its a toy because of the lack of speed and memory(even the titanium model, try to solve a 21 degree polinomial ecuation in it... and yes some people has to deal with those monsters in real life situations) but its easier to get aroud with it.
Pros:
Easy to use.
Updatable.
Lots of free apps.
cons:
It doesnt work well with hyperbolic functions(EE needs those).
too slow.
