Algebra 63 - Gauss-Jordan Elimination with Curve Fitting

The lecture introduces curve fitting using cubic polynomials, explaining how to find a mathematical function that fits a set of data points. It covers real-world applications, solving for coefficients using Gauss-Jordan elimination, and handling inconsistent systems. The lecture also explores systems with infinitely many solutions and concludes with a preview of quadratic functions.
