(1) Use the Laplace transformation to find the renewal function H(t) of an ordinary renewal process whose cycle lengths have an Erlang distribution with parameters n = 2 and λ.

(2) For λ = 1, sketch the exact graph of the renewal function and the bounds (3.138) in the interval 0 ≤ t ≤ 6. (Make sure that the bounds (3.138) are applicable.)
