  Started the video, paused, went to my marker board and solved it! Then skipped to the end and I saw that I got it right. First time I have solved one of these on my own. Your help has been HUGE! Thank you!

  Spent the last week panicking about Laplace transforms — all of that anxiety vanished after watching this video! Thank you

  I dont really know why professors in my uni just does not go into this much depth into explaining a single example. The way he teaches me reminds me of my high school teacher who used to make complex problems easily digestible.

  I want to comment that you can use residue method to get A/s.<br><br>To do so, &nbsp;we will consider P(s) = (s^3 + 2s^2 + 1)/(s^2 + 4). <br><br>Then, we can differentiate P(s) but we have to divide it by n! where n is the number of times differentiation can occur. (In this case, n= 1) because s is only repeated once.<br><br>P&apos;(s) = [(3s^2 + 2s)(s^2 + 4) - 2s(s^3 + 2s^2 + 1)]/(s^2 + 4)^2<br><br>From the previous cover-up: s = 0 so we have P&apos;(0).<br><br>Then, you can plug 0 into your function. After applying differentiation. You&apos;ll be surprised you&apos;ll get the same answer for A.
