Yes, by partial fraction
#52 Re: Help Me ! » Laplace differential equation » 2013-12-17 22:57:20
Yes I would be grateful
#53 Re: Help Me ! » Laplace differential equation » 2013-12-17 22:25:37
I will leave it at this level
#54 Re: Help Me ! » Laplace differential equation » 2013-12-17 21:00:12
What you think of using laplace inverse for this equation ?
(We usually take Laplace inverse for last equation and convert it to f(t) function )
#55 Re: Help Me ! » Laplace differential equation » 2013-12-17 16:38:55
I do not know this is home work 
#56 Re: Help Me ! » Laplace differential equation » 2013-12-17 07:37:07
Yes, that were I stopped , if you can complete it or give me same examples I would be grateful to you
#58 Re: Help Me ! » Laplace differential equation » 2013-12-17 06:40:14
Yes , but this equation is tf'(t)....
I'll upload my solution when I end

look at First Derivative it the same way to solve the question
#60 Re: Help Me ! » Laplace differential equation » 2013-12-17 06:12:35
I think it solved by definition of Laplace
#61 Re: Help Me ! » Laplace differential equation » 2013-12-17 06:04:08
at L[ty'] I get y''(s) and stopped ,,, sorry just sin(2t) not sin(25)
#62 Re: Help Me ! » Laplace differential equation » 2013-12-17 05:56:39
Yes , I solved the first equation but with out result and I need to see other solution or another problems like this
#63 Re: Help Me ! » Laplace differential equation » 2013-12-17 04:59:21
Yes, I know it but how to solve it if the function f(t) multiply by f(s)
#64 Re: Help Me ! » Laplace differential equation » 2013-12-17 03:26:28
Any information about the way of solution
#65 Re: Help Me ! » Laplace differential equation » 2013-12-17 03:05:19
I want solved using Laplace transform to solve differential equations, please any help I need solution of it as soon as possible

Q.1 y'' -(1-t)y'+y=sin(2t)
where y(0)=y'(0)=5
t
Q.2 y''+[sin(t)∫exp(t)*sin(lnt)dt]y'+y=sinh(t)
5
where y(0)=y'(0)=2
