Perhaps if we'd had this calculator in high school we would have done much better in trigonometry. The Texas lnstruments Tl-83 is an ideal unit for any math student, combining powerful features for graphing and statistical analysis.

The LCD screen displays 16 characters over 8 lines. Though the Tl-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 Tl-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 Tl-83's Draw operations allow you to annotate graphs. Along with the advanced math and science features, the Tl-83 also includes such financial functions as cash flow, amortization, and time value of money.

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

Buyer's feedback: - * Item did not work ...
I received the above item with a battery that was corroded. I installed a new, uncorroded battery into the graphing calculator but the calculator did not work. I contacted the company and they reported that in 2 years they have never had a complaint. They did instruct me to mail it back with a copy of the e-mail regarding the problem with the calculator. We shall see how the replacement works.
