Answer:

The Laplace transform is L(e^{-t} sin3t)=(\frac{3}{(s+1)^{2} +9} ).

Step-by-step explanation:

Laplace transform is an integral transform that converts a function of a real variable to a function of a complex variable.

We need to determine the Laplace transform.

t.e^-t.sin3t

We will use identities here:

L(sin3t)=\frac{2}{s^{2} +3^{2} }

Now,

L(e^{-t} sin3t)=\frac{2}{(s+1)^{2} +3^{2} }=\frac{2}{(s+1)^{2} +9 }

And

L(te^{-t} sin3t)=-\frac{d}{ds}

L(e^{-t} sin3t)=(\frac{3}{(s+1)^{2} +9} )
