This is the mathematical reference book for the first and the second year graduate students who want to learn more about the application of certain techniques, to do calculations which happen to have interesting results in mathematical analysis.It is well known that we often need to establish some new sequences to converge to some fundamental constants with increasingly higher rate.Mathematical constants play a key role in several branches of mathematics.In this theory, an important concern is the definition of new sequences convergent to the mathematical constants with quicker rate of...
