Approximation by Orthogonal Polynomials
Requires a Wolfram Notebook System
Interact on desktop, mobile and cloud with the free Wolfram Player or other Wolfram Language products.
The Gram–Schmidt process is used to obtain orthonormal polynomials with respect to the 
norm. These polynomials are then used to interpolate a number of functions; a logarithmic error plot is provided.
