Operation that consists of constructing or estimating the value of a function for a value of the variable taken between two discrete values in the interval in which the relationship was established.
Example
Starting from the values of \(\log(5)\) and \(\log(6)\), we can estimate using interpolation the value of \(\log(5.5)\):
\(\log(5.5) ≈ \log(5) +\dfrac{\log(5) + \log(6)}{2} ≈ 0.738\).
