Click the Run button
Type cmd then press enter
In the command box type the drive letter for your CD Rom Drive, followed by a colon (example, D:) then press enter
Type tiinteractive.exe /quiet then press enter
Wait 5 minutes then close the command box
TI interactive should be now installed

If it doesn't work, e-mail me at brumed@verizon.net

If they are the original blue controllers, rekove the bottom of the controller and run a fine piece of sand paper folded so both sides of the sand paper make contact through the contacts, this should clean them where they will work, If this does not work, the wiring or the controller circutry is defective.

In parametric functions, the variables x and y are both functions of an independent variable, called t, and that usually represents the time. The default variable in parametric functions must be called t. You can enter the limits you want. However if you type in 2 Pi it will be converted on the entry line to 6.28. The default tstep is 0.13 which is about pi/24. I fail to see what the commotion is about.
In this representation of the witch of Agnesi, the variable t is between 0 and 4Pi, and the step tstep is 0.13, a little less that pi/24
Reset your calculator and restart

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.

If you're not trying to graph a function, please tell us exactly what you are trying to do when you get this error.
