Inverse Laplace : with Convolution

[QUOTE="vela, post: 5290683, member: 221963"] Is the asterisk supposed to denote multiplication or convolution? You need to use parentheses as appropriate. Assuming the asterisk is supposed to be multiplication, what you wrote means $$F(s) = e^{-3s}\left(\frac 3s + \frac{15}{s^2} + 25\right),$$ which is quite different from what you intended. Is there some reason you're not simplifying 15/5? Why do you think something's wrong? Besides the problems LCKurtz pointed out with what you've written, did you notice that when you wrote "=(3*cos(5*t)+15/5*sin(5*t))*s(t-3)," you never said what it was equal to and that you're using * to mean both multiplication and convolution? You should make an effort to be less sloppy, especially when you're trying to communicate with others. [/QUOTE]
