The application of alternate Series in evaluating definite integral
LI Xiao-fei · Journal of Huanggang Normal University · 2013
According to the problem that integral from n=a to b((sinx/x)dx) and integral from n=a to b(sinx~kdx)cannot integrate in elementary function,we study the periodicity of sine function,obtain the estimated value by using their characteristic and the astringency of alternate series.
