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. Imposing y(0) = 1 gives C= e. Example 0.3.

Integrating factor method

Generalizing this approach the idea is to find some modified vector field F ˜ with F ˜ ( u 0 , 0 ) = F ( u 0 , t 0 ) , which approximates F around u 0 and hopefully captures key features of F . Free ordinary differential equations (ODE) calculator - solve ordinary differential equations (ODE) step-by-step Direct Method The trick is to represent the left side of the Standard Form of the equation in the form of the product rule, while the right side is some function of the independent variable ( ). To do so, we multiply the entire differential equation with the Integrating Factor 𝑃 to get the equation: we ﬁrst ﬁnd the integrating factor I = e R P dx = e R 3 x dx now Z 3 x dx = 3lnx = lnx3 hence I = elnx3 = x3. Then we multiply the diﬀerential equation by I to get x3 dy dx +3x2y = ex so integrating both sides we have x3y = ex +c where c is a constant.
