Abstract: In this paper, we examine numerical methods for finding the principal value of Cauchy-type integrals for various density functions. Exact analytical expressions and approximate methods with estimates of errors are presented.

Keywords: Cauchy-type integral, Dawson function, majorant test for uniform convergence, Gaussian hypergeometric function, principal branch of the logarithm
