Pronunciation: /ɪnˌtɜr pəˈleɪ ʃən/ ?
Interpolation is a process for approximating the value of a function that is
difficult to find. For example, say you want to approximate the value of
|1||Start with 1 and 4.||Find numbers larger and
smaller than 3.7 that have easy to calculate square roots.|
||The square root of 1 is 1.|
||The square root of 4 is 2.|
||What part of the way is 3.7 between 1 and 4?|
||About how much more is the square root of 3.7 than the square root of 1.|
||Approximate the square root of 3.7. The actual value of the square root of 3.7 is about 1.9235.|
