Thank you, Carl Love. I did define _F1 to be the identity function,
but it didn't work beautifully like your definition.

Thank you, Preben!

What does " modify the character styles appropriately" mean? It means nothing to me. Which style is it talking about? All I get is a listing of fonts. I enter a word and change its font to my liking. What did I just do? Which font in my display of maple programming have I changed? What does "Export your style set" mean? How come there is no example on the planet Earth that shows you how to do these things?

acer,

Thank you so much for your help. Luckily, in the type of the inverse Laplace
transforms that I am considering, the solution always contains "RootOf" for the complex roots.
So, I convert the solutions to strings and look for "RootOf" in them. When I find one
occurrence, I avoid printing the respective solution.
Thank you again!

Yes, acer. I just discovered that. I used sol:=solve([eq1,...,eq6],[a,b,c,d,f,g]); This is how I got the list that I can handle.
Thank you!
Would you also be kind enough to tell me how to get only real solutions?
Thank you again!

I think I have an answer to the first question. I can get the result of "solve" as a list, and then I can get the number of
elements of the list of solutions, or the (i,j)-th element of each solution list.
Thank you.

That is not case, @acer.

The terms that are  missing are not there anymore. They leave no trace.
It is OK, though. I can solve the problem by using lists.
Sorry for bothering you.
Thank you!

## @acer You are right, acer. The func...

You are right, acer. The function g is a sum of q terms..
Each term is a fraction of two polynomials of s. I just want to know if
the nth such term, n<=q, exists.
Thank you!

This is great, Robert. However, every time I print the equation, with its ivp conditions,
I get

I need to remove of that phrase.
Thank you again!

They are just ordinary derivatives, John. Thank you for "ToJet".

This is all just great, acer!
It works averywhere.

Thank you very much!
