33.
A system is at rest for t < 0. It is given by 
If steady state is reached at t = 0, then the value of angle A is given by
If steady state is reached at t = 0, then the value of angle A is given byAnswer: Option
Explanation:
= U(t) sin (2t + A)
y(s).s + 2y(s) = 
char.eqn S + 2 = 0
jω + 2 = 0 j2 + 2 = 0
1 + j = 0 tan-1(1) 45°.
