Follow-up Comment #4, bug #56069 (project octave):
Mike and Colin,
Thank you for your suggestions and recommendations. I will go with
laplace(sin(w*t), t, s)
That works!
When I encountered the problem, I couldn't figure out for laplace(sin(w*t))
how the symbolic processor knew which variable was the integration variable
and which was the complex frequency -- it didn't occur to me that there would
be an alphabetical rule that caused my "a" example to work differently than my
"w" example. I like the recommendation you gave --- it's clean and it
explicitly sets the proper variables.
Thank you for your help.
