Polynomial Curve Fitting with Mathcad

Polynomial+Curve+Fitting+with+Mathcad%0D

This worksheet delivers a introduction to the theory behind polynomial curve-fitting. It gives a derivation of the governing simultaneous linear equations for determining the best-fit coefficients of a 2nd order polynomial, and provides a program that calculates the best-fit coefficients of an arbitrary order polynomial.

A comparison with the coefficients produced by Mathcad's built-in commands is also given.
