Derivative vs Polynomial Regression

The DerivativeCalculus is a simple but elegant app to find the derivatives of complex multivariable functions. You can find the partial derivatives of a multivariate function and share it with others or save it locally. You can create a beautiful high quality partial derivative tree and share it with others or save it locally. Derivatives are shown in beautifully written mathematical expression It automatically saves your hard work locally on your device so you can come back and pick up from where you left off as your great effort will not be lost. This app also has a Study page to help you learn important differentiation rules like, product rule, chain rule, quotient rule, ect. This app is perfect for students learning calculus. Sharpen you brain by using this app and learning about the calculus. This is an app for all student groups. From high school to college to university students. Be creative. Enjoy the app!

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.
