Assignment #6 Due: 12:30 pm on Friday July 29, 2011. No late assignments will be accepted. 1. (a)Solve the following IVP using the Laplace transform. Write your answer as a piecewise-deﬁned function (i.e. without unit-step functions). 2 y 00 + y 0 + 2 y = δ ( t - 5) , y 0 (0) = 0 ,y 0 (0) = 0 . (b) Interpret this d.e. as a modeling for electrical circuit or spring system. (c) Discuss (interpret) the solution of this d.e. for the system you give in (b) for 0 t < 5, shortly after t = 5 and also as t → ∞ . 2. Use the formula for the derivative of a Laplace transform to show that if
