Values of some integrals



Could someone with macsyma/mma/maple evaluate the following integrals
for me?  I'm verifying some of the defint routines and I'd like some
independent verification of these integrals.

integrate(x^(2*%i+3)/exp(%i*x^3/2),x,0,inf);

integrate(x/(sinh(x)-%i),x,minf,inf);

integrate(x^3*exp(%i*x^3/2),x,0,inf);

integrate(x^2*exp(%i*x^3/2),x,0,inf);

integrate(x^k*log(x)/(x+3),x,0,inf);

Thanks,

Ray
