integral bug in xCas or HP PRIME

[robmio]

Thanks for confirming, Albert Chan. However, apart from this type of bug (which leads to incorrect results in calculating the Laplace transform of functions such as: "t^n*ln(x)", with "n∈N" and "n >= 0"), another limit of xCas, which I hope will be overcome sooner or later, is the calculation of limits of the type: "lim (Ei(i*x), x, +infinity" --> Pi*i, in the context of inverse Laplace transforms.
What do you think about it?
