I personally don’t know the answer so i can’t help
6a. By the convolution theorem,

6b. Similarly,

7. Take the Laplace transform of both sides, noting that the integral is the convolution of
and
.


where
. Then
, and

We have the partial fraction decomposition,

Then we can easily compute the inverse transform to solve for f(t) :

Answer: 
Answer:
you can always use sin or cos or tan in these situations
Commutative property is "a + b = b + a"
Therefore your answer is 1. 5 + 6 = 6 + 5
