Graphing Calculator AR vs Polynomial Regression

Graphing Calculator lets you visualize algebra and calculus interactively and experience 3D graphs in augmented reality on devices which support AR. Graph functions, implicit relations, parametric curves and surfaces, inequalities, points, vectors, contour and density plots, color maps, vector fields, ordinary differential equations, surfaces of revolution, coordinate transformations, conformal maps and complex-valued curves, surfaces, and ODEs. Use rectangular, polar, cylindrical, or spherical coordinates. Solve equations numerically, graphically, or symbolically. "Graphing Calculator is one of the best examples of elegant power and clean user interface of any application I've seen." - Bruce Horn, creator of the Macintosh Finder.

Polynomial Regression is your calculator and, more importantly, learning tool. You will be able to: * Construct polynomials of up to 20 degrees from either real or complex roots. * Interpolate polynomials from points by Lagrange, Newton or Vandermonde methods and Quadratic or Cubic splines. * Perform Least Squares approximation by orthogonal projection, with or without QR factorization, or partial derivatives. * Learn about each of the algorithms with derivations, proofs, step by step demonstrations, and visual tools. * Have an option to enter data by either typing or tapping on XY plane, and save data sets between program runs.
