Hello.
Alas, Mathematica 4.2 does sadly remind me Mathematica 3.0.
Something like a small breakthrough plus ocean of bugs
(as compared with the previous release).
In particular,
$Version
"4.2 for Microsoft Windows (February 28, 2002)"
LaplaceTransform[Exp[-z^3]/z^10, z, p]
(Null*p^9)/(39366*Sqrt[3]*Pi) + (9/80)*p*Gamma[1/3]*\
HypergeometricPFQ[{-(8/3)}, {2/3, 4/3}, -(p^3/27)] +\
(3/56)*p^2*Gamma[-(1/3)]*HypergeometricPFQ[{-(7/3)},\
{4/3, 5/3}, -(p^3/27)]
Question 1. What is the origin of Null?
Question 2. What is the easiest workaround for this bug,
that is how to calculate the correct answer?
Thank you for your help in advance!
Best,
Vladimir Bondarenko
