## Homework Statement

Find the Laplace transformation of the following function by using iterations of integration by parts:

f(t) = tsin(t)

## Homework Equations

## The Attempt at a Solution

I know how to do integration by parts (as learned in calculus) but have never seen a funtion that has dependence on t in three places ie. definition of laplace transform is ∫f(t)e^(-st)dt which for this problem would go to... ∫tsin(t)e^(-st)dt...how would I go about starting this? thanks
