Homework Statement
Im having trouble finding ways to manipulate equations to fit something from the table
The two I'm stuck on are these
1. [itex]\frac{1}{s^{2}- 2s + 3} (\frac{1+(s^{2}+1)e^{-3\Pi S}}{(s^{2}+1)})[/itex] = Y(s)
2.[itex]\frac{1}{s^{2}- 2s + 2} (\frac{s}{s^{2}+1} + s - 2)[/itex] = Y(s)
Homework Equations
These are the IVPs i got them from
1. y" - 2y' + 3y = sint + [tex]\delta[/tex](t - 3*pi)
y(0) = 0
y'(0) = 0
2. y'' - 2y' + 2y = cost
y(0) = 1
y'(o) = 0
The Attempt at a Solution
I tried all sorts of things like multiplying the equations out
i still can't seem to find a way to comfortably manipulate it to match anything on the laplace table
can some one help or give me a tip?
