Interpolation in Excel and Python (ChEn 263 - Lecture 18, Full Lecture)

This video contains a lecture for Chemical Engineering 263 (Undergraduate Numerical Tools) at Brigham Young University. In the lecture, I cover the basic theory behind interpolation including the polynomial uniqueness theorem, Runge's phenomenon, and the differences between interpolation and fitting. I also do an example of linear interpolation by hand, and use Python to fit splines (piecewise, polynomial interpolating functions).

I. Basic Concepts of Interpolation: 1:11
II. Interpolation by Hand and in Excel: 21:47
III. Interpolation in Python: 31:56
