Polynomial Curve Fitting with Mathcad File Size 0.30 mb 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. Download Estimate File size: 303.69 KB and 44 seconds. [56Kbps] and 4 seconds.
