    I have a general question about Laplace transforms. Lets say that I want to transform -20e^(-10t) to the s domain. Do i just do -20*(1/(s+10)) or do i need to see that -20e^(-10t) is the derivative of 2e^(-10t) and then use the derivative property and multiply F(s) by s after i transform? Any help is greatly appreciated. Thanks!

    You go with your first option. Why would you be concerned about the derivative?
