Question about Texas Instruments TI-84 Plus Calculator

Re: graphing

Press STAT, go to Edit, then enter x values in L1 and y values in L2 (other lists can be used too, but these are the default ones).

Next, go to STAT PLOT, pick a plot, turn it on, select the type, data lists (x and y should be L! and L2 already; if not, change them), and mark type.

Finally, hit graph. You may need to adjust window settings to see all of the points. If you get a DIM MISMATCH error, check to make sure that there are the same number of entries in each list, and that only the plots that you are using are turned on.

If it is just a matter of not seeing all points, just set the zoom to **ZoomStat.**

Use the (-) key located just to the right of the decimal point key to enter the negative sign, not the - key located to the right of the 6 key.

- Install the TI Connect software on the computer.
- Connect the calculator to the computer using the Silver Link cable or the USB direct cable.
- Run the TI Connect software and let it recognize the Calculator.
- Once this is done, create the graph on the calculator, and click the screen capture button in TI Connect.
- Save image in jpeg format.
- Send it to the printer to print or insert it in a text document which you then print.

You're probably trying to graph a function that does not involve stat plot features. You can correct this by turning off the stat plot features. Press "2ND" "STAT PLOT" and then select 4:PlotsOff.

You need to adjust the range of your graph. On the graph menu press range then enter the values of x and y. Set Xmin to -4 and Xmax to 60, and ymin to 2.5 and ymax to 3.5. IThis should adjust it properly, as you say.

If you have used or just run the Transfrm Application, you will no longer be able to draw more than one graph.

To restore the native OS graphing capabilities Uninstall the Transfrm Application. Here is how to do it.

Hello,

I am sorry to disappoint you, the nDeriv ( function can only calculate numerical derivatives of an expression at a point. The dy/dx can do the same thing (calculate the first derivative) at one point on a displayed graph. It can be activated for graphs by pressing TRACE, then [2nd][CALC][6:dy/dx]. If you need the derivative at more than one point you have to press [2nd][CAL] [6:dy/dx] again.

What I said above concerns the native abilities of the calculator. There may be applications you can install to allow computation of 2nd derivatives. look for them on the TI site, or the archive section of ticalc.org. Try deriv

Hope it helps.

First click on the Y= button and enter an eqation or goto stat and hit enter and type the points. Afterwards goto Y= then hit plot1 so it is highlighted and hit zoom and then zoomstat and you will have grphed your points.

That is because you don't have the right amount of points. Either delete one point or add another point. Then try to graph it.
