6. Divide by the integrating factor to get the solution: y= B(x)e− R a(x)dx + C 3e − R a(x)dx. For the fourth step, you must remember the product and chain rule of diﬀerentiation as well as the Second Fundamental Theorem of Calculus. The Second Fundamental Theorem of Calculus states that for a continuous function f(x), d dx Z f(x)dx= f(x). 1
