It doesn't matter. Just isolate Y(s) by dividing both sides by (s+4). Then use partial fractions to compute the inverse Laplace Transform of the RHS.In the third line, what is S+4 the laplace transform of?
I'm not exactly sure what you are trying to ask here. If you are asking whether [itex]4Y(s)=\frac{1}{s+4}[/itex], then the answer is no.so is the laplace transform of 4y = 1/s+4? then how does it end up being a factor of y(s)?
Oh! Now I see what you were asking.The working i attached wasn't carried out by me. I havent gotten as far as
[tex]
(s+4)Y(s)=\frac{17}{s^2+1}+1
[/tex]
someone else did. i want to know how they got there.
im unsure as to how they got y(s)[s+4]
i also dont know what the laplace transform of 4y is.
