The TI-83+ is a
calculator made by
Texas Instruments.
There is much
software that has been released for the TI-83+ that expand it's
capibilities and make it more like the
infamous TI-89. Three of the more notable ones are as follows:
Symbolic, by Detached Solutions;
Gives access to the other
trigonometric functions:
cosecant,
secant,
cotangent, their
inverses, their
hyperbolic versions, and the inverse hyperbolic versions; finding the
derivitive of a
function; finding the length of an
arc from one point to another on a function; a
simplification tool much like the TI-89's; and a few other useful tools.
Omnicalc, by Detached Solutions;
Allows for different
base calculations,
prime factorizations,
modular artithmatic,
square-rootsimplifacation, a really nice
parentheses assistant, a menu for entries instead of repeated 2nd-enter pressing,
lowercase letters, a
clipboard, a
custom menu and much more.

Makes your TI-83+ calculator more like a TI-89 in the way you can display your
calculations. It displays whatever you type in like a TI-89 would, which is with much more
clarity than you would usually have with the TI-83+'s basic displaying, allowing for
fractions, square-roots and many other things to show up much better.
