The concept of exact differential equations can be extended to second order equations. Consider starting with the first-order exact equation: Since both functions , are functions of two variables, implicitly differentiating the multivariate function yields Expanding the total derivatives gives that WebThe original equation (3xy + y²) + (x² + xy) y' = 0, turns into (-3x² + x²) + (x² - x²) y' = 0, that is, -2x² = 0, or simplified x = 0. That is, x = 0 (the vertical Y-axis) is in fact a solution of our differential equation. But is this solution already included in our Ѱ (x,y) = C equation, that is, is x = 0 a solution for it? nmwg.cap.gov https://hutchingspc.com

WebNov 5, 2024 · This equation is true only for an exact differential because we derived it by assuming that the function exists, so its mixed partial derivatives are the same. We can use this relationship to test whether a differential is exact or inexact. If the equality of Equation holds, the differential is exact. If it does not hold, it is inexact.
