You can see the similarity when you write it out. The gradient field: F (x,y)=grad (f)= The DE: M (x,y)dx+N (x,y)dy=0 with solution f (x,y)=c. Nettet15. jun. 2024 · The integrating factor is r(x) = e ∫ p ( x) dx = ex2. We multiply both sides of the equation by r(x) to get ex2y ′ + 2xex2y = ex − x2ex2, d dx[ex2y] = ex. We integrate ex2y = ex + C, y = ex − x2 + Ce − x2. Next, we solve for the initial condition − 1 = y(0) = 1 + C, so C = − 2. The solution is y = ex − x2 − 2e − x2. perth biodesign

An integrating factor is any expression that a differential equation is multiplied by to facilitate integration. For example, the nonlinear second order equation admits as an integrating factor: To integrate, note that both sides of the equation may be expressed as derivatives by going backwards with the chain rule: NettetIf is such that the differential equation M dx C N dy D0 is exact, then is called an integrating factor of (1). Obviously, an exact differential equation remains exact when multiplied by a con-stant. In other words, all constants are integrating factors of an exact differential equa-tion.
