(x*y^2+x)dx+(y-x^2y)dy=0
(x*y^2+x)dx+(y-x^2y)dy=0-The equation is M(x,y)dx N(x,y)dy =0 , with M = 4xy 3y^2 x , M_y = 4x 6y N = x(x 2y) , N_x = 2x 2y # M_y The equation is not exact but ( M_y N_x )/N = 2/x , depends only on x and leads to the integrating factor IF = x^2 One obtains the equation P(x,y)dx Q(x,y)dy =0 with P = 4yx^3 3y^2x^2 x^3 , P_y = 4x^3 6yx^2ANSWER IS Solution For a differential equation M(x,y) dx N(x,y) dy= 0 The necessary and sufficient condition for exact differential equation is ∂M/∂y = ∂N/∂x Here the equation is not exact if M(x,y) dx N(x,y) dy = 0 is of the from f(x,y)y dx g

Solve the differential equation dy/dx = (2y^2cos x y sin2x 2cos xsin^2x)/sin^2x asked in Differential equations by Nakul01 ( 369k points) differential equationsFactor integrador = e ^ ∫ 1 / y dy = e ^ ln y = y Multiplicar por y y² (x y 1) dx xy (x 3y 2) dy = 0 (xy² y³ y²) dx (x²y 3xy² 2xy) dy = O La ecuación ahora es exacta La solución es F (x, y) = C, donde ∂F / ∂x = M (x, y) = (xy² y³ y²) F (x, y) = ∫ (xy² y³ y²) dx Explanation x dy dx = 2x2y y, separating the variables 1 y dy dx = 2x2 1 x so dy y = 2x2dx dx x, integrating ∫ 1 y dy = ∫2x2dx ∫ 1 x dx, we have lny = x2 lnx C Which gives ln y x = x2 C eln y x = ex2c theory of logs ie, y x = ex2c and so,y
But if I expand the bracket $(xy)^2$ before integrating I will get $$\varnothing_1=\int Mdx=\int (xy)^2dx=\int (x^22xyy^2)dx=\frac{x^3}{3}xy^2x^2y$$ Wich will lead to the solution $$\varnothing=\varnothing_1\varnothing_2=\frac{x^3}{3}xy^2x^2yy=Constant$$ What is the wrong step ?
