Cheap functional graphing calculator
1 of 1 found this helpful This calculator is much cheaper than Texas Instruments', but the features are comparable. The largest inconvenience in using it comes from the fact that 99% of people use TIs. So It may be difficult to learn how to use it. I strongly recommend to buy this calculator used. The money you save is worth the hassle.
