Question: How do I calculate the invlaplace of tanh(s)?

Iwould like to calculate the inverse laplace transform of the expreesion which I call T.

< T:=tanh(s):

To do this I use the code "invlaplace" to solve it.


But it returns "invlaplace(tanh(s),s,t)".Done nothing.How to get its mathematical expression? I am really interested to get it.

PLZ help me in anyway as you can as I am completely stuck.
