Wrath of Math | Least Squares Fit of a Polynomial | Linear Algebra @WrathofMath | Uploaded 2 months ago | Updated 2 hours ago
We go over how to find the least squares solution to determine the coefficients of a polynomial of best fit for a given set of data points. We will do an example finding the best fitting quadratic to a set of four data points. #linearalgebra
