Integrating factor differential equation

Nettet1 Answer Sorted by: 6 Integrating factor μ = μ ( ω), we get from equation d μ μ = M y − N x ω x N − ω y M d ω. By replacing known values M = 2 x y 3 + y 4, M y = 6 x y 2 + 4 y 3 , N = x y 3 − 2 y, N x = y 3 into equation, we have d μ μ = 6 x y 2 + 3 y 3 ω x ( x y 3 − 2 y) − ω y ( 2 x y 3 + y 4) d ω. Nettetfrom the equation: psi-y = x^3 + (x^2)*y + 5. after you equalize the psi-y expressions, you get: h' (y) = 5. so, h (y) = 5y. psi = (x^3)*y + 1/2(x^2)* (y^2) + h (y) psi = (x^3)y + …
