Given the loop transfer function
G(s)H(s) = k/s(s+3)(s+4)(s+5)
(a) Sketch the root locus plot for G(s)H(s).
(b) What is the system gain at s = -1+ 2i?
(c) Calculate the settling time.
(d) Find the gain margin for the gain selected in part (b).
The number ways of choosing 2 boys and 2 girls in a class for a game of mixed doubles is 1620. Then, what is the number of ways of choosing 2 students in the class?
