Summary.
Starting with some results of Lyness concerning the Euler-Maclaurin expansion of Cauchy principal value integrals over \(\left( 0,1\right)\) it is shown how, by the use of sigmoidal transformations, good approximations can be found for the Hadamard finite-part integral \({\int\!\!\!\! \scriptstyle{=}\;} _0^1\left (\phi \left( x\right) /\left( x-c\right) ^2\right) dx,\) where \(0 < c < 1.\) The analysis is illustrated by some numerical examples.
