Using only the definition of the Laplace transform, and showing your work, find the Laplace transform of:
(t^2)u(t-(1/4) where u is the Heaviside function.
I don't know what it means for u to be the Heaviside function and I have the definition of Laplace transforms right in front of me, and I am not sure how to use it to solve this. Any help would be greatly appreciated. Thanks!
