vanhees71, thanks for your reply. I maybe formulated my question wrong, concerning the first question above. I needed to find an "general solution for y'-3y'+2y = 2ex".
And this general solution do i get by the theorom "the sum of "the sum of one special solution of the inhomogeneous...
Reading my first calculus course at my first semester as an "Computer Engineer". In Sweden it's called "Single Variable Calculus".
I have my first exams next week and i have been solving differents of DE's.
y'-3y'+2y = 2ex
But now i have encountered a problem in my "partikulär lösning"...
