Y''-6y'+9y=t y(0)=0 y'(0)=1
notka56 [123]
L[ y(t) ] = Y(s) 

L[ y' ] = sY-y(0) = sY-0 = sY 

L[ y'' ] = s^2*Y - sy(0) - y'(0) = s^2*Y - 1 

laplace trasform both sides 

L[ y'' - 6y' + 9y ] = L[ t ] 

= L[ y'' ] - 6 L[ y' ] + 9 L[ y ] = 1/s 

= [ s^2*Y - 1 ] - 6[ sY ] + 9Y = 1/s 

( s^2 - 6s + 9 ) Y - 1 = 1/s 

⇒ ( s^2 - 6s + 9 ) Y = (1/s) + 1 

⇒Y = [ 1 / ( s(s^2 - 6s + 9 ) ) ] + [ 1 / ( s^2 - 6s + 9 ) ] 

Let inverse laplace trasform , find y(t) : 

y(t) = L^(-1)[ Y(s) ] = L^(-1) { [ 1 / ( s(s^2 - 6s + 9 ) ) ] + [ 1 / ( s^2 - 6s + 9 ) ] } 

= [ (1/3)*t*e^(3t) - (1/9)*e^(3t) + (1/9) ] + [ t*e^(3t) ] 

= (4/3)*t*e^(3t) - (1/9)*e^(3t) + (1/9)
