Hi

in here

http://en.wikipedia.org/wiki/Final_value_theorem

why in the example he says 0 then he says 3 ?

isn't it (steady state)s to zero ?

(EDIT) : also , how can i evaluate Lim(s=>0){-s/(s+2)}

 

He must be giving s/s a value of 1 instead of undefined.

For Lim(s->0){-s/(s+2)}, just plug 0 into s. The result is 0/2 = 0.
