Total Posts: 9 | We spent our entire algebra II class trying to figure out how to change the y= to x= in the y= editor, and the most uninclined person done it and doesn't remember how he did it. He did it on a TI-84 Plus, do any of you know how to successfuly do this on the TI-89 Titanium? |

Total Posts: 623 | You mean you want the calculator to graph equations with respect to y instead of x? Did I follow that correctly?
Parametric is the only graphing mode involving "x=" that I know of...

Total Posts: 9 | We need to change the y to a x, the teacher is a math major, retired from a university, thats besides the point lol. We know it CAN be done, we just cant figure out how to do it, and i really need help because me and another student are the only ones in the school with TI-89 Titaniums. |

Any my comment about the teacher is if they don't know enough about the calculator to properly teach using it, they shouldn't be using it. |

Total Posts: 9 | lol, he DOES know how to do it, just not on the TI-89 Titanium.... thats what we need help with, we can do it perfectly fine on the TI-84 Plus in its y= editor.
He has the TI-84 Plus. I have the TI-89 Titanium. |

Total Posts: 9 | not calling you stupid Andy, but yes it is possible, on the TI-84 Plus, we can go to y= editor, go up to where the plots are, go to the left and there is a x=, press enter on top of the x= and it changes to a y=, and where it use to say y=, are all now x=. But the TI-89 doesn't have that... |

Total Posts: 939 | Oh really? What OS version are you running, because unless it's 2.30 or higher, it doesn't exist without an add-on app. Perhaps TI added some more fun stuff and didn't tell us about it either. :-\ |

Total Posts: 9 | I have no idea what the OS is on the TI-84 Plus, but i will look and tell you tomorrow. Im running OS Version 3.10 on my TI-89 Titanium.
It just may be something someone added, because the 84 plus that it was done on is a school's calc, and was loaned out to other ppl last year, so, they may have added something or altered the OS. |

Total Posts: 310 | I've got a bit about the workaround methods to graph in terms of y here: http://www.technicalc.org/tifaq/?p3.htm#10.3.4 The thing that puts an actual x= screen on the calculator is the inequality graphing 83+ Flash App. TI's idiotic Flash Apps that screw with the y= screen are Fun Fun Fun, people turn on the Transformation Graphing app accidentally all the time and then don't know why it won't let them do more than one function at a time. |

Total Posts: 507 | yup... "Inequalz" will give you X=, but its an irritating app in my opinion... useful at times, but nothing the TI-OS cant normally do, for the most part... |

Total Posts: 939 | Unless there's an 89 version, which there may well be, you can't do it. Not only will the calc not let you send it over, but if you would manage to somehow send it over it could royally screw the 89 up. The 83+ and 89 use different processors and vastly different OSes. |
