Hello :) Is there any way to evaluate the definite integral Integrate[ (Sinh[t] Sin[t])/(11 Cosh[2 t]-7)^(3/2), {t,-Infinity,Infinity}] in a closed form via Mathematica? The Integrate command just can't do this integration symbolically and I think some trick may require. I appreciate your help. Wien Hong
