please show the entire problem and parts a and b, and if there is more, please show that also

thanks for the reply but part a and b are not related with the question

parts a and b may not be relevant, but tables 2.1 and 2.2 are
i suggest you look for something related to t^3 u(t) in the tables
that may point you in a good direction

there is a theorem about multiplying a function of time f(t) by time t
that should help

yes tables are shown the shortways of doing it but the point that i asked how do we derive the laplace transform by taking the integral of u(t) three times.
