Question

what is the laplace inverse of (s^4+6s-18)/(s^5-3s^4)?

Answer 1

use partial fractions
and take s^4 common from denomiator it will be easy to solve

Answer 2

and then use the formulae that laplace inverse of 1/s = 1 and laplace inverse of 1/s^2= t etc and laplace inverse of 1/s-3= \[e^{3t}\]

Answer 3

the answer is (e^(3t) )+t^3

Answer 4

would you please give me the solved question

Answer 5

do you know how to make partial fractions??

Answer 6

yes

Answer 7

then use partial fractions and it will be easy use the formulae i mentiond above

Answer 8

is it form bsc?? methods

Answer 9

s^4+6s-18=A/s+B/s^2+C/s^3+D/s^4+E/s-3

Answer 10

yes right and then find A,B,C,D,E AND IT WILL BE 101 PERCENT SIMPLE

Answer 11

ok thanks alot
