Hello ,
I am trying to linearize [itex]\dot{x}[/itex]+√x = 0. The only equilibrium point is at x=0; but the derivative is not defined at this point. Does any body have a suggestion? Regards.

Why are you trying to linearize it?

Linearization problem
[itex]\sqrt{x}[/itex] cannot be linearized at x= 0 precisely because its derivative does not exist.
