Homework Help: Find the function(antidiff)

  1. Apr 15, 2009 #1
    1. The problem statement, all variables and given/known data

    [tex]f:\Re\rightarrow\Re[/tex]
    [tex]e^xf(x)+e^xf\prime(x)=f(x)[/tex]
    Find f(x)

    2. Relevant equations



    3. The attempt at a solution
    i don't know if [tex] f(x)\neq 0[/tex] so i can't divide by [tex]f(x)[/tex] which would make things pretty simple.

    Try this:

    put all f '(x) on the left side, and f(x) on the right side
