Question

Hi everyone. Can someone help me check this inverse Laplace transform?

Answer 1

\[e^-3s/s^2\]

Answer 2

\[(e ^{-3s})/(s^2)\]

Answer 3

So I though the -3 would indicate t+3 in time domain and the inverse laplace of 1/s^2 is the unit ramp function r(t) or tu(t)

Answer 4

so r(t+3)......my solution says r(t-3)

Answer 5

uc(t)f(t-c), c = 3

f(t) = t^n

...
uc(t) (t-3)^n

Awesome thank you!
