Lagrange's interpolation formula

Research output: Contribution to journalArticle

Abstract

In issue 31(2) of the Australian Senior Mathematics Journal, Kok (2017) describes a useful four-step process for investigating number patterns and identifying the underlying function. The process is demonstrated for both linear and quadratic functions.

With respect to the quadratic example, I provide an additional idea relevant to step 3 and demonstrate the use of Lagrange's interpolation formula as an alternative method for completing step 4.
