comment Finding fundamental set of solution of higher order differential equation
Sorry, I don't quite understand why I don't need to use Wronskian to conclude this. In which case then do I need to use the Wronskian to conclude that something is a fundamental set of solution? Thank you

How to know when I need to apply the method of variation of parameter?

comment Why is the particular solution of $y'' - 4y' +3y = e^t$ not in the form of $Ae^t$
"both $e^t$ and $te^t$" meaning the homogenous equation looks like $Ay'' - By' + Cy = e^t + te^t$, then the particular solution will look like $t^2e^t$, am I correct?

and if $te^t$ is already in the homogeneous solution, we will need to multiply by one more $t$ making it $t^2e^t$?

Thank you. I feel ashamed that I did not see this.
