1. Use the Laplace transform to solve the initial value
problem.
?"+4?′+3?=1−?(?−2)−?(?−4)+?(?−6), ?(0)=0, ?′(0)=0
2. Use the Laplace transform to solve the initial value
problem.
?"+4?=?(?), ?(0)=1, ?′(0)=−1
= { 1, ? < 1
where ?(?) = {0, ? > 1.
Use the Laplace transform to solve the following initial value
problem:
?″+6?′+58?=?(?−4)
?(0)=0,?′(0)=0
(Notation: write u(t-c) for
the Heaviside step function ??(?)uc(t) with step at ?=?t=c.)
