Line 53:
We choose this integrating factor because it has the special property that its derivative is itself times the function we are integrating, that is:
 
:<math>\frac{d{\mu}}{dx} = e^{\int p(x)\, dx} \cdot p(x) = \mu pq(x)</math>
 
Multiply both sides of the original differential equation by ''&mu;'' to get:
