## farahkibri Group Title if F(t) and G(t) are of exponential order and L{F(t)}=L{G(t)} prove that F(t)=G(t). Can anyone help me prove this question plz =) 2 years ago 2 years ago

1. UnkleRhaukus

is L for $$\mathcal L$$aplace transform ?

2. farahkibri

yes

3. UnkleRhaukus

when you say $\mathcal L\{F(t)\}=\mathcal L\{G(t)\}$ do you mean $\mathcal L\{f(t)\}=\mathcal L\{g(t)\}$$\qquad F(s)=G(s)$?

4. UnkleRhaukus

or do you mean the laplace transforms of, the laplace transforms of the functions are equal /

5. farahkibri

laplace of this function are equal and i want to prove that the function also equal...but dunno to start it....can u help me plz

6. farahin_kibri

i am the same person that ask for this question.............actually this is a laplace transform theorem of derivatives............i need to prove this theorem.......the laplace for F(t)=G(t)
