Initial Conditions in Laplace Transform of Second Order Differential Equations

Click For Summary
SUMMARY

The discussion focuses on the application of Laplace Transform to second-order differential equations with specified initial conditions. The equations presented are y' + 2y = 2(1 - e^(-2t)) with initial condition Y(0) = 0, and y'' - 2y' + y = t + e^t with initial conditions y(0) = 1 and y'(0) = 0. Participants clarify the distinction between initial conditions in the time domain versus the frequency domain, emphasizing the importance of correctly applying the Laplace Transform to solve these equations.

And also:
y`+2y=2(1-e^-2t) Y(0)=0
y¨-2y`+y = t+e^t y(0)=1 and y`(0)=0

Please help me out here folks ;)

It's a bit unusual to have an initial condition in the frequency domain. Are you sure the initial condition for the first DE is $Y(0)=0$? Or is it $y(0)=0$? In any case, what do you get when you Laplace Transform the entire equation? (For each DE.)
