Short answer; you can't. But you can purchase (or borrow) a TI84 calculator and use the TI83's transfer cable to transfer data from the 83 to the 84 to your mac computer (the TI84 comes with a USB transfer cable).
The TI-83 calculator uses 4 AAA batteries.
You cannot. A calculator is programmed. It is made to calculate correctly.
There are online graphing calculators. However, as of writing, there is no emulated TI83 that runs within your browser. On the other hand, if you have a Ti83, it is possible to copy its ROM to run an emulated TI83 on your desktop via one of many emulators.
get a windows emulator on you mac got into the emulator download kodu an run it :D
It will depend on the class. Nothing is impossible without the TI83, but some classes might require it so you can graph and write programs to go along with the math curriculum.
Some TI83's can be set up differently, so it is highly recommendable to read the user guide for the TI83 in question. The user would need to go into the VarStat option and enter all the appropriate fields to have the calculator bring in the appropriate variables and totals.
the best free emulator would be QEMU. But IEmulator V is a pay emulator that works amazingly.
Yes. DeSmuME is available for Mac OS X.
Yes. There is about 7 Mac emulators for PC.
Yes, Desmume
Quit the emulator. The cheat will naturally disable.
