Why the laplace transform of a derivative not work when I added a constant value to it?

Hi,

Why when I added a constant value a to a derivative I see that the laplace transform of a derivative did not work as expected? Am I doing wrong something? Or?

It seems like the derivative of b(x) is sometimes not recognised as such.

Check the labels of your variable, especially the x'es. All your x'es should be of the same label.

I checked x-es labels...they are the same:

Still there is a different one. the (x) between brackets is a '(variable)', not a 'variable'.

 

If that doesn't help, file a bug report.
