Are you sure you wrote #1 correctly? If so, it's very easy to answer.

oh yes I missed a t for the (3 +1), supposed to be (3t + 1). My teacher had made it look confusing to me I guess.

Thank you so much, got the same answer except for the b part of the final answer, I got 12cos(3t+1)sin(3t+1) which is the same thing?

I wrote 12sin(3t+1)cos(3t+1), you wrote 12cos(3t+1)sin(3t+1). That's the same thing, just the factors are ordered differently.
