If * denotes convolution then you're right.

I'm posting your PM here because it's against PF rules to address homework (or homework-type) questions by PM:

First of all thank you for taking the time to answer my question.The Y(s)/s+1 is a part of a Laplace equation and i have to find out which is the DE that gave that Laplace equation.So i inverse-Laplace the given equation to find the DE. My answer is still correct right?

Thank you and sorry for bothering you,
Rforrevenge

P.S:Sorry for my bad English

With regards to the above, I don't think I can answer it definitively because I don't know what is the original question, so clearly I can't tell if you are right.

the original question is that i have to find the DE of that Laplace transform
s*Y(s)+Y(s)/s+1=X(s)
 

Related to What Is the Inverse Laplace Transform of Y(s)/(s+1)?

1. What is the Laplace transform?

The Laplace transform is a mathematical tool used to convert a function of time into a function of complex frequency. It is commonly used in engineering and physics to solve differential equations and analyze systems.

2. Why is the Laplace transform useful?

The Laplace transform is useful because it simplifies complex differential equations into algebraic equations, making them easier to solve. It also allows for the analysis of systems in the frequency domain, which can provide valuable insights into their behavior.

3. How is the Laplace transform calculated?

The Laplace transform is calculated by integrating the function of time multiplied by the exponential of negative time over a range from 0 to infinity. The result is a function of complex frequency.

4. What are some real-world applications of the Laplace transform?

The Laplace transform has many real-world applications, including in circuit analysis, control systems, signal processing, and image processing. It is also used in the study of heat transfer, fluid dynamics, and quantum mechanics.

5. Are there any limitations to using the Laplace transform?

While the Laplace transform is a powerful tool, it does have some limitations. It can only be used for functions that are defined for all positive time values and have a finite number of discontinuities. It also requires knowledge of the initial conditions of the system being analyzed.
