Question

F(s)=10/(s+4)(s+3)^3
any one?
I'm really bad in Math but I never hate it..
Step by step solution could enhance my understanding...

Answer 1

What are you trying to solve exactly @zami92

Answer 2

this into laplace equation @kirbykirby
I found it is difficult to change to laplace..yet, I'm stuck before I can proceed to laplace transformation.

Answer 3

Wait you're trying to find the inverse Laplace transform of \(F(s)\) ?

Answer 4

Yes yes..that's what I'm try to say...

Answer 5

I think the best thing to do is to try and break up your fraction by doing partial fractions. And then apply the inverse laplace transform on each fraction

Answer 6

how I can apply the inverse laplace transform @kirbykirby ?

Answer 7

there is usually a table with common laplace transforms. Here is a pretty good one: http://tutorial.math.lamar.edu/Classes/DE/Laplace_Table.aspx

So you have F(s), and inverse Laplace transform is doing the reverse action of a Laplace transform. But your F(s) is hard to manipulate right away, so a common trick to do when you have a rational function with factors, is to apply partial fraction to break up the fraction to a sum. It might be easier to understand what to do once you find the partial fraction decomposition of F(s)

Answer 8

I'll try it first..and I will respond tomorrow.. It's 1.24am now in Malaysia..soo I will tag u again okay.. I have to sleep since I got class tomorrow.

Answer 9

All right ;)
