GRACIAS

Hello, I was testing the program with some class exercises, I found this case in which it cannot solve and it tells me undefined. attached image. I tried the same exercise in wolfram alpha and symbolab and they solved it without problems. Any ideas or suggestions?

I think that some variable used in the program is not local and has a value which leads to an error.
Maybe you should restart your calc or try in another folder.

By the way, this decomposition doesn't need any program since its roots are real and can be computed without square roots.
Just type

Code: Tout sélectionner

expand((s-4)/(s^2*(s^2-9)),s)

and it will do...

Hello, thanks yes indeed: expand(((s+4)/(s^(2)*(s^(2)-9))),s) works, I knew about expand but not about (,s). In any case I need the inverse of Laplace so I will use the other program for Laplace transforms.
