please help me this Inverse Laplace Transformation question

Find the Inverse Laplace Transform of this function

1/(((s+1)^2)(1+e^(-2s)))

I just don't know how to separate it , please help me

Yes, But I read a few books about it, still don't get how to do that...
 
Maple 9 doesn't want to solve it

Hi;
Is it really
<br /> \frac{1}{(s+1)^{2}(1+e^{-2s})}<br />
Maple 9 doesn't want to solve it.
Can you check it just in case.
Max.

yes... the question is right.
 
First put the (1+exp(-2s) factor into the numerator and expand as a series. the function appears to be a series of square wave pulses, which are probably modified by the (s+1)^2 factor.
 
There is the following linear Volterra equation of the second kind $$ y(x)+\int_{0}^{x} K(x-s) y(s)\,{\rm d}s = 1 $$ with kernel $$ K(x-s) = 1 - 4 \sum_{n=1}^{\infty} \dfrac{1}{\lambda_n^2} e^{-\beta \lambda_n^2 (x-s)} $$ where $y(0)=1$, $\beta>0$ and $\lambda_n$ is the $n$-th positive root of the equation $J_0(x)=0$ (here $n$ is a natural number that numbers these positive roots in the order of increasing their values), $J_0(x)$ is the Bessel function of the first kind of zero order. I...
Are there any good visualization tutorials, written or video, that show graphically how separation of variables works? I particularly have the time-independent Schrodinger Equation in mind. There are hundreds of demonstrations out there which essentially distill to copies of one another. However I am trying to visualize in my mind how this process looks graphically - for example plotting t on one axis and x on the other for f(x,t). I have seen other good visual representations of...
