Chapter 4 / Variation of Parameter for higher order eqautions
« on: November 18, 2020, 12:26:03 PM »
Since we have learned the variation of parameter method for second and third order equation, I just want to confirm whether my idea is correct or not. For fourth order eqatuion or higher, should we compute the det of 4 by 4 matrix or even higher to use this method? Is there any general theorem for this method?
