Question

Please use the below definition of Laplace transform (DO NOT USE TABLE RULES)

F(s) = L[f(t)] = integral from 0 to infinity e^-st*f(t)dt

 

Please find y(t) using Laplace transform in the picture.

 

Eg. Integral from 0 to infinity e^(-st) * 1 dt  when f(x) = 1.

 

-st = u

-sdt = du

 dt = (1/-s)du

so, (1/-s)integral from 0 to infinity e^u du

= (1/-s)*[{e^-(st)}infinitiy - {e^-(st)}0]
