Dear All I have a function that to be integrated with respect to s , the function is : (2*E^(((-Sqrt[p] - V)*x)/2)*Î³*DifferentialD[(p - V^2)/4])/(-Sqrt[p] - V) What i need to to do is actually change the varible s into p (before the integratio) according to the relation p=4*s+V^2; How can i automatically do that (changing the variable) using mathematica ? Remember that i have the term "ds" which i should take care of when i make the change . Any help in this regard will be highly appreciated Many thanks in advance HMQ
