Approximation Theory : From Taylor Polynomials to Wavelets

This concisely written book gives an elementary introduction to a classical area of mathematics approximation theory in a way that naturally leads to the modern field of wavelets. The exposition, driven by ideas rather than technical details and proofs, demonstrates the dynamic nature of mathematics...
