Question:How do I solve tanhs=C3*s ?

I would like to solve the following equation that I call equ?

> equ: = tanh(s)=C3*s

To do this I use the code “solve” to solve it. C3 is constant.

> sol: =solve (equ,s)

RootOf(_Z*C3*(exp(_Z))^2+_Z*C3-(exp(_Z))^2+1)

I then get the RootOf expression. How to get its mathematical expressions? I am really interested in getting it.

Please help me in anyway you can as I am completely stuck
