A method is proposed for the evaluation of the integrals Cin(z) and Si(z), using integer-order Bessel functions. The results add to the repertoire, and are well suited for use in Excel spreadsheet applications, where functions of the Bessel type are part of an easily accessible library. © 1990-2011 IEEE.
