The needs of automatic digital computation have spurred an enormous revival of interest in methods of approximating continuous Functions by Functions that depend only on a finite number of parameters.
Because Approximation theory is an area of mathematics with important practical applications in computation, the author takes.
This concise but wide-ranging text provides an Introduction to some of the most significant of these methods, with particular emphasis on Approximation by polynomials.
