Re: Which is better? Ti-83 or ti-85??



There are two more things that I forgot to add to the TI-83-better-than-TI-85
list:
Sequence graphs
DelVar command

The TI-86 has a DelVar command, but not Sequence graphs.

The TI-85 is definitely much better, overall. It is just a much better
machine.

Advantages of TI-85 over TI-83: (in no particular order)
No limit to number of variables (they can be named)
Lowercase letters, Greek, and international symbols
Higher resolution
Better matrix math
Unit conversions
Number bases
Bit manipulation routines
Advanced equation solving functions (up to 30th order polynomials and 30
simultaneous equations)
Bit manipulation functions
Vector math
Better calculus
Numbers in scientific notation can be as high as 10^999 instead of 10^99
Equation variables so you don't have to write a program for every formula you
have
Custom menu
Commands and variables can be typed; they do not have to be selected from a
menu
Physical constants
Differential equations

Advantages of TI-83 over TI-85: (in no particular order)
Advanced statistics
Finance
More last entries and answers saved than just one
Graph table
Split screen
"Nicer" list and matrix editors
More graph styles
Draw text on graph

Unless you need the statistics, it is quite clear that the TI-85 is better. TI
themselves must think that because they numbered the TI-83 lower than the
TI-85, even though it is newer.
