Solve Laplace Transform of t sinwt w/ Theorem 1.31

In summary, The problem at hand is to determine the Laplace transform of t sinwt using theorem 1.31, which is the general differentiation method. The corresponding equations for this method can be found on the provided link, however the link is currently broken. The suggested solution is to transform the sin function, then apply the corresponding Laplace function of t to the transformed sin function. However, it is mentioned that there may be easier theorems to use for this problem, but the instructor specifically wants this method to be used.

Shown on linked page



[h2]The Attempt at a Solution[/h2]

I do not understand how to start this becasue I do not have a function to a power, I have a multiplication of 2 functions. I know there are better theorms for this porblem but he specifically said we need to use this one, can anyone help me out?

Thanks in advance.

transform sin function then apply the corresponding laplace function of t to the transformed sin function.

I don't think that is what this theorm calls for, can you verify from th link?

He said that he wants us to do it this way even though there are easier ways, go figure...
 

Related to Solve Laplace Transform of t sinwt w/ Theorem 1.31

What is the Laplace Transform of t sinwt?
