The initial-value theorem for a function f(t) with suitable transform F(s) gives f(0+) as?

  • Alim s->0 of sF(s)
  • Blim s->infinity of sF(s)
  • Clim s->0 of F(s)/s
  • Dlim s->infinity of F(s)/s
Report an error
Correct Answer: B. lim s->infinity of sF(s)
Explanation: Under the theorem's applicability conditions, f(0+)=lim as s approaches infinity of sF(s).
