A negative unity feedback loop with input R(s), output Y(s) and error E(s) is placed around the system
\(H(s)=1/((s+p_{1})(s+p_{2})...(s+p_{q}))\)

(a) Find the transfer function E(s)/R(s).

(b) For this system to respond to inputs of the form r(t)=t^n (t=>0 and n<q) with zero steady-state error, what constraints are placed on the open-loop poles p.1 .... p.q?
