Like.
Thinking about it more closely, we want ##c_1y_1 + c_2y_2## to be a particular solution. But we're happy if it's only determined up to a... -
haushofer replied to the thread Undergrad 2nd order ODE's, variation of parameters and the notorious constraint.Yes, thanks a lot, you're absolutely right. Reading your post I redid the calculation and indeed was missing a factor of p(x) which...
