Explanation about Initial Value Theorem and Final Value Theorem
INITIAL
VALUE THEOREM AND FINAL VALUE THEOREM
Initial value theorem
If
then
initial value of x(t) is written as

Proof:
Differentiation property
of Laplace transform is

Take limit δ → ∞ of the
above equation

L.H.S of (2) can be
written as

Substitute (3) in (2)

Final Value theorem

Proof:
Differentiation
property of Laplace transform is given as,

L.H.S of (2) can be
written as

Let us substitute (3)
in (2)

Hence proved.
