I was doing a exercise and I couldn't finish it because I needed to do this inverse Laplace transform, and I got no idea how to do it. I tried convolution, I expanded the sin to complex exponential and got nothing in the end. Can anyone help me?

1What does "Laplace transform ... from $s$ to $t$" mean? – user Mar 23 '20 at 13:07

When you do the inverse you get a f(t). – Takeshii Mar 24 '20 at 20:10

And what are $r,D,x$? – user Mar 24 '20 at 20:14

You can consider them as constants, only s is the variable. – Takeshii Mar 25 '20 at 21:12

Is there any reason to have both $x$ and $D$ as constants? – user Mar 25 '20 at 21:18

Yes. Thank you for your time, but I don't need an answer anymore. I changed my approach on the exercise and I didn't use this inverse laplace. – Takeshii Mar 26 '20 at 21:57
