    Calculate Laplace Transform with Im(k)=0, Im(p)=0

    without ambiguity: \int {0} {\inf} { (exp(-rk)/r)*(1/r+k) }dt r = sqrt ( p^2 + (vt)^2 ) p.s. my calculation is big, that is why I don't insert its.

    Calculate Laplace Transform with Im(k)=0, Im(p)=0

    Thx for help, but I don't simplify your answer. I'm going use the answer (if it possible) in math model. Numerical answer is suit, but if it in the form: f(k,p)*numerical_answer I try to apply the teory residues for a solve. What do you think about? P.S. I should note that the...

    Calculate Laplace Transform with Im(k)=0, Im(p)=0

    You undestand me right! I didn't use other version, but I found the new release 5.1 at http://www.wolfram.com

    Calculate Laplace Transform with Im(k)=0, Im(p)=0

    I have a proplem to analitic calculate this : (k/p^2)*LaplaceTransform[Sqrt[z^2+2p*z]/(z+p)],z,k]+ (1/p^2)*LaplaceTransform[-Sqrt[z^2+2p*z]/(z+p)^2],z,k] Im(k)=0, k>0 Im(p)=0, p>0 The Mathematica 5 doesn't calculate this. Very glad to help.
