Approximating Functions Using Polynomial Interpolation 12/3

December 1, 2015

Approximating Functions using Polynomial Interpolation
Thursday, December 3 from 3:15-4:00 p.m., Whitman 183 (CAMS)

Associate Professor Yajun Yang will present this Department of Mathematics Seminars. The title of the presentation is “Approximating Functions using Polynomial Interpolation.” All interested students and faculty are welcome. The abstract of the talk is as follows: “When we think about approximating a function, what typically comes to mind are Taylor polynomial approximations. However, using Taylor polynomials for approximating functions is not necessarily the most effective approach. Instead, we look at a different approach known as interpolation methods. We use the Lagrange interpolating polynomials to approximate various functions such as exponential and logarithmic functions, sinusoidal functions. We will examine the behavior of the error function associated with the approximations. Interactive spreadsheets will be used to investigate dynamically the way that the interpolating polynomial approximates the functions and to find the best polynomial to approximate a given function on a given interval.”
