I Variable coefficients. Read: I The direction field.

Since there exist positive integers a and b such that x a y b is an integrating factor, multiplying the differential equation through by this expression must yield an exact equation. THE METHOD OF INTEGRATING FACTORS: the initial value problem. THE EQUATION: dx dt +p(t)x = q(t). THE INITIAL CONDITION: x(0) = x o. THE INTEGRATING FACTOR: µ(t) = exp Zt p(s)ds . REWRITE DIFFERENTIAL EQUATION: d dt (µ(t)x(t)) = µ(t)q(t).

Problem 11 | Integrating Factors Found by Inspection Equation of a curve with given equation of slope and passing through a point The Determination of Integrating Factor First Order Linear Differential Equations How do we solve 1st order differential equations? There are two methods which can be used to solve 1st order differential equatio Second solution: Integrating factor method. The integrating factor is A(x) = Z exdx= ex. Multiply both sides of the equation by eex and obtain eexy 0 = 0 ⇒ eexy= C ⇒ y= e−exC.
