Question

5,
(s + 1)(5 + 2s + 2)​

Answer 1

The ans is 7s + 2s^2 +4s+7

Answer 2

Answer:

Step-by-step explanation:

(a) L −1

2

s

3

(t) = L −1

2!

s

3

(t) = t

2

(b) L −1

3

s

2 + 9

(t) = L −1

3

s

2 + 32

(t) = sin(3t)

(c) L −1

s − 1

s

2 − 2s + 5

(t) = L −1

s − 1

(s − 1)2 + 22

(t) = e

t

cos(2t).
