Error function

  1. Aug 7, 2009 #1
    1. The problem statement, all variables and given/known data
    Consider the initial value problem y'+e^(x)y=f(x), y(0)=1.Express the solution of the initial-value problem for x>0 as a non elementary integral when f(x)=1 and also in term of erf(x)

    Can somebody please help me solve this question?

    Thanks!

    [tex]\frac{dy}{dx}+P(x)y=Q(x)[/tex]

    In this form use an integrating factor

    [tex]e^{\int P(x)dx}[/tex]
