Can you tell me what to press if i want to draw a tangent at x=1, and the equation is y=x^2?
I know how to graph the function, i just need help with drawing the tangent.
Thanks.
Here is a screen capture from my 92. They are essentially the same.
Graph what you want, then press F5. You will see a drop down list. Locate Tangent. I think it is option A. It will ask where, type 1, then hit ENTER.
i have this same problem too... i tried that, and then typed in one after graphing the first function and selecting tangent from the drop down list. i pressed enter and nothing graphed, but it said y=2.x-1
what does that mean?
and how do you get the line to be drawn tangent to the parabola?
