A unity feedback control system has forward loop transfer function as e-Ts/s(s+1). Its phase value will be zero at frequency ω1. Which of the following equations should be satisfied by ω1?
ω1 = cot(Tω1)
Tω1 = tan(ω1)
ω1 = tan(Tω1)
Tω1 = cot(ω1)
ω1 = cot(Tω1)
Tω1 = tan(ω1)
ω1 = tan(Tω1)
Tω1 = cot(ω1)
