Chebyshev approximation is a part of approximation theory, which is a eld of mathematics about approximating functions with simpler functions. This is done because it can make calculations easier. Most of the time, the approximation is done using polynomials. In this thesis we focus on algebraic polynomials, thus polynomials of the form p(x ...
