Introduction
Both of the interpolation programs in this chapte - Cubic Splines and Exact Polynomials - can be used in either of two ways, depending on the type of data you have.
The Interpolation Programs
When you select { INT } from the MATHEMATICS menu, the calculator displays a menu that lets you select either the Cubic Splines or the Exact Polynomials program.
The Cubic Splines { CUB } program can be used with:
- Known data points. (Data points are considered "new" data.)
- Known second derivatives. (Derivatives are considered "old" data.)
- Known data points. (Data points are considered "new" data.)
- Known coefficients. (Coefficients are considered "old" data.)
