Consider the function F (s)= 5/s(s2+3s+2), the initial value of f(t) is:
A. 5
B. 5/2
C. 5/3
D. 0
Answer:D
Consider the function F (s)= 5/s(s2+3s+2), the initial value of f(t) is:
A. 5 B. 5/2 C. 5/3 D. 0
Explanation: For initial value theorem in which time is at t =0 and for the frequency which is the inverse of time, the value of s is replaced with infinity and hence the value obtained is 0.
