Hi guys, could you help me solve this simple problem, what happens is that I have a little doubt with the defining intervals of the function, thanks

Find the Laplace transform of the given function

g(t)

= 0 t < 3

= t t ≥ 3

Hey frankitm.

Hint: Look at the Heaviside function:

Indeed, your fuction can be written as

where is the Heaviside funcion. The Laplace transform of your function is

You can do that integral by parts.
