Question about Texas Instruments TI-89 Calculator
How do I graph an equation with TI 89 The equation is S=48.4-6.1cos(pi*t/6)? Thank you so much!
Just open the Y= equation editor and enter your equation. Use X for T. Make sure the angle unit is in radians.

The first solution will allow you to watch your
calculator graph two equations simultaneously rather than finishing one
before graphing the next; it won't solve the problem of having the
calculator unselect one equation when you select a second. To fix
that problem, try the following:
In order to select additional graphs, the Transformation Graphing App will need to be uninstalled from the TI-83 Plus Family and TI-84 Plus Family. Uninstalling the App does not erase it from the calculator, it disables it from interfering with the normal graphing modes. Below are the steps to successfully uninstall the App.

SOURCE: graphing multiply equations
When you go to Y=, you should get a list that says:
etc. You just enter the first equation into the Y1= space then hit ENTER and it will go to Y2=. Enter the second equation there. After you have entered all of your equations, push GRAPH and they should come up in order but they will all appear.
Also, make sure your window is set appropriately so that you are able to see all of the graphs.
Lastly, when you look at your Y= screen, are there funny looking arrows before the Y=? If so, do this:
Hope one of these are helpful!!

This is simple... Back up all RAM, (press second+, then 2, then 1, press enter to back up something if backed up it will have a star by it) Then clear your RAM (pull out your batteries while the calc is still on or press second+, then 7, then 1)
Hope this helps!

you have one of your stat plots on that is what is messing it up. So either turn off the stat plots. Or just reset your calculator. hit 2nd then the plus (+) key then 7 then 1 then 2. Good luck
