 The modified Bessel functions of the second kind K_m can be represented by: I tried to calculate this integral with Mathematica Version 12: f[t_] := Exp[-x*Cosh[t]]*Cosh[m*t]; Integrate[f[t], {t, 0, Infinity}] Unfortunately Mathematica does give no result by solving the integral above. Can someone explain me, how to solve this integral with Mathematica. Thank you for your help in advance. Ruediger
