Question

inverse laplace transform of (-2e^-2s)(s-4)/(s-5)^3

Answer 1

is it
\[\frac{ -2e^{-2s}*(s-4) }{ (s-5)^3 }\]

Answer 2

yes, it is.

Answer 3

according to matlab
-e^(5t-10)*(t-2)*t*theta(t-2)

but not sure, i havent dont it for a while

Answer 4

sorry..i didn't use matlab..by the way how can i do partial fraction for the dinominator??

Answer 5

for the rational expression \[\frac{ s-4 }{ (s-5)^3 }=\frac{ A }{ (s-5) }+\frac{ B }{ (s-5)^2 }+\frac{ C }{ (s-5)^3 }\]

Answer 6

tq very much...that's what i'm looking for.. =D
