I have a few questions about finding the general solution of first-order linear differential equations..
please help, I have no clue!! =/
it doesn't make sense though..
is there a simpler way of explaining it?
I don't understand what "the integrating factor" is in the first place..
(with practice, you will be able to recognize the integrating factor immediately, but let's go through the method to see it)
the integrating factor is
multiply through by the integrating factor, we get:
now the left hand side is the result of differentiating by the product rule, thus
integrate both sides, we get:
the others are done similarly
