Role of integration factor

  1. May 30, 2009 #1
    e^{\int (2t-1)dt}=e^{t^2 -t}
    then we do

    \frac{d}{dt}[e^{t^2 -t}]=...
    i was told that i will get the original left side of the equation times p.
    i didnt get the same result

    what is the role of integration factor

    An integrating factor is a function with which you multiply the differential equation to help facilitate the solving of the differential equation.

    There was a similar question here a few days ago, where I did part of the calculation.
