    Wronskian

    Hey guys I understand most of how to do a Wronskian but I don't understand where you get an integrating factor. Going to upload the example sheet if someone could explain the steps I've circled I'd be much obliged.

    When you have a DE in the form, y'+p(x)y=f(x) , the integrating factor is \displaystyle\exp{\left(\int p(x)dx\right)}

    \displaystyle\int\frac{d}{dx}\left[\exp{\left(\int p(x)dx\right)}y\right]dx=\int\left[\exp{\left(\int p(x)dx\right)}f(x)\right]dx
