Solution 12060: Interpolation Calculations on the TI-89 Family, TI-92 Family, and Voyage™ 200.
How do I perform interpolation calculations on either the TI-89 family, TI-92 family, or Voyage 200?
Neither the TI-89 family, TI-92 family, or the Voyage 200 have a built-in interpolation function.
However, students, educators, and other users of the TI-89 family may find third-part sources available on the Internet for retrieval of a
user-defined interpolation program for the TI-92 family and Voyage 200.
