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.
