Solution 12144: Locating the Variable List/VARS Key on the TI-89 Family, TI-92 Family, and Voyage™ 200 Graphing Calculators.

Where is the VARS key located on the TI-89 family, TI-92 family, or Voyage 200?

There is not a [VARS] key on TI-89 family, TI-92 family, or Voyage 200 calculators. Since the TI-89 family, TI-92 family, and Voyage 200 have the built in CAS (Computer Algebra System) and the ability to perform symbolic manipulation, any variable needed can be manually typed using the alpha-numeric keys. For instance, if on the TI-83 family or TI-84 Plus family the instructions state to press the VARS key and select Y1, y1(x) can simply be typed using the alpha-numeric keys on the TI-89 family, TI-92 family, or Voyage 200.

Please see the TI-89 family, TI-92 family and Voyage 200 guidebooks for additional calculator information.
