Texas Instruments TI83 Graphing Calculator

The LCD screen displays 16 characters over 8 lines. Though the TI-83's keyboard layout might seem daunting to those who've never laid eyes on a graphic calculator before, the helpful, if intimidatingly thick, manual will get you up and running quickly.

The TI-83 includes function, parametric and polar, and sequence plot modes. You can store, graph, and analyze up to 10 functions, 6 parametric and polar functions, and 3 sequence functions. The TI-83's Draw operations allow you to annotate graphs. Along with the advanced math and science features, the TI-83 also includes such financial functions as cash flow, amortization, and time value of money.

The included input-output cable lets you link the TI-83 with another TI-83 or a TI-82 for data sharing, and the optional TI-Graph Link software lets you transfer files to a PC.
