Edit detail for #361 integral yields strange error message revision 1 of 2

changed:
-
It seems that all current CAS have a problem with this integral:
\begin{axiom}
integrate(1/(-3+v^3)*v/(-4+v^3)^(1/2),v)
integrate(1/(-3+v^3)*v/(-4+v^3)^(1/2),v=0..1,"noPole")
\end{axiom}
However, at least the error message could be better...
