HELP! Inverse Laplace Transform

Patton84

I'm having some trouble getting the inverse Laplace to the following problems...I need some help

F(s)=24/s^5

F(s)= 4/[((s-2)^2)+25

F(s)= s/(s-1)(s+1)

For the first one, consider L{tⁿ} works out to be for n>0.

For the second one what is

[tex]L^{-1} (\frac{1}{s^2+k^2)[/tex]

for the third one, split into partial fractions.

would this be right for the third one

A/s-1 + B/s+1 = s

A/s-1 + B/s+1 = s

Yes that's correct.

No that is wrong, the right formula is:

[tex]\frac{s}{(s-1)(s+1)}=\frac{A}{s-1}+\frac{B}{s+1}[/tex]

from which you need to determine A and B.

Oops I thought he multiplied it out and set it equal to s
