How to do integration symbolically with cauchy principal values
Dear everyone, I meet a cauchy integration when calculating optical functions with Kramers-Kronig integration: \!\(\(Ïµ\_1\) \((x)\) = constant + \(2\/Ï?\) P \(â?«\_x0\%â??\(\( Î¾*\(Ïµ\_2\) \((Î¾)\)\)\/\(Î¾\^2 - x\^2\)\) \[DifferentialD]Î¾\)\) How to do it symbolically in Mathematica? And how to develope software with Mathematica with interfaces like VC++ ?
