Multiplication by s
et if 0 <t < 1
e ift >1
3. Let f(t) = {e
and g(t) =
Find F(s) and G(s) and
show that the rule L[f (t)| = -fo + sF(s) holds for g but not for f. Why is it so?
4. Given f(t) :
S2t if 0 <t <1
It
find (a) F(s), (b) L[f (t)|. Does the rule
if t > 1,
L[f(t)] = -fo + sF(s) hold? Explain.
