Homework Equations
not sure how many there are.
The Attempt at a Solution
So I made the system into a unit feedback system despite its hint...and it turned out..strange.
Another thing i don't understand is, with the conditions that the questions, i only get one equation to solve for k and [tex]\alpha[/tex], are there any others that i might be overlooking?
