Equações Diferenciais não exatas e o fator integrante ➡️ EP 36

DIFFERENTIAL EQUATION 🔴 NOT EXACT How do I convert a non-exact ODE to an exact one? Sometimes it is possible to convert a non-exact differential equation to an exact one. This process is done by multiplying the equation by an appropriate integrating factor. M(x,y)dx + N(x,y)dy = 0. There must be a function μ(x,y) where the equation μ(x,y) . How do I calculate the integrating factor? When to use an integrating factor? In mathematics, especially in the theory of differential equations, an integrating factor is a function used to facilitate integration and solve the equation or find a conservation law. How do I know if a differential equation is exact? We say that the equation Mdx+Ndy=0 is exact if: My=Nx. Examples: The differential form 3x2y2dx+2x3ydy=0 is exact because there is F(x,y)=x3y2 whose exact differential coincides with the left-hand side of the given equation.
