This paper aims to present a Clenshaw–Curtis–Filon quadrature to approximate thesolution of various cases of Cauchy-type singular integral equations (CSIEs) of the second kind witha highly oscillatory kernel function. We adduce that the zero case oscillation (k = 0) proposed methodgives more accurate results than the scheme introduced in Dezhbord at el. () and Eshkuvatovat el. ( Cited by: 1. 'One of the strengths of the book is the attention given to the history of the subject and the large number of references to older literature. At the same time the author succeeds in giving an introduction to the current state of the art in the theory of Volterra integral equations and the notes at the end of each chapter are very helpful in this respect as they point the reader to the Cited by:   Fie also solves a large class of integral equations with moderately smooth kernel function on [0,\infty).
