So... Got my second diff eq test back today. 113/150.. Lost 31 points because it seems, contrary to my personal belief, I can't do Laplace transforms to save my life.
Therefore, I was hoping someone could help me. Here's the two functions I got very very wrong:
Some quick notes. Y = Laplace of y,U(t-2) is that switch function that is zero when t < 2 and 1 when t>=2, and L = laplace transform
Here are my answers/ways I tried to solve them:
It seems that is entirely wrong. I'm not sure why you can't do that and I would love some input.
It seems that is also entirely wrong. As I said earlier. I would LOVE some help!
Thanks for answering back. No, those were not convolutions. They are simple multiplications. If anybody would be so kind could they explain how to correctly solve those two problems? I would really really appreciate it. The rest of my diff eq class uses laplace so I need to understand this stuff!
