Texas Instruments TI-81 Questions and Answers


#1 Is it possible to do slope on this calculator?

I assume by this you mean whether the TI-81 can automatically tell you the slope of a function at a point by either inputting coordinates or selecting a spot on its graph, without you having to calculate anything? I think so, but I am unsure. I would check but cant do so now because it looks like I ran out of stock of TI-81
