the question... i've measured C(x), wich is equal to li(I(x)), where li denotes the logarithmic integral function. I would like to compute I(x)= li^(-1) (C(x)) how can i compute the inverse of the logarithmic integral function ? Is there a function Inverse[_function] ? thanx a lot Arthur Capet, ULG, Belgium
