Hi,
I think, there is a new bug in Maxima 5.30.0
(Standard Version for Windows).
I cannot answer the request for a case differentiation
in the following expression any more
(neither in wxMaxima nor in the command line program):
(%i1) integrate(sin(omega*t)*exp(-s*t),t,0,inf);
Is s positive, negative or zero?
An answer is not accepted (neither n, nor z, nor p).
The old Maxima version 5.27.0 works fine.
