X2+y2+1dx+xx 2ydy0 Non Exact

Solving a non exact differential equation given the form of its integrating factor We want an exact equation of the form M dx N dy, and since it is not exact, we multiply it by the IF, I(x, y) = x^p y^q and want to solve for p and q to make it exact, so have x^p y^q ((3y2xy^3)dx(4x3x^2y^2)dy=0) Differential Equations, can't find.

X2+y2+1dx+xx 2ydy0 non exact. Dy dx = g(x)f(y) The steps to solving such DEs are as follows 1 Make the DE look like dy dx = g(x)f(y) This may be already done for you (in which case you can just identify the various parts), or you may have to do some algebra to get it into the correct form 2 Separate the variables Get all the y’s on the LHS by multiplying both sides by 1. They give you the integrating factor is x2, so multiply the whole equation by said factor to get (1y 2 /x 2)dx (12y/x )dy = 0 Now, check for exactness again, dM/dy = dN/dx (these should be partial derivatives) dM/dy = 2y/x 2 dN/dx = 2y/x 2 Therefore this equation is now exact, and solve it like you would any other exact equation.

Answer I read the following equation M(x,y)dx N(x,y)dy =0 , with M(x,y) = y(y 2x 2 ) , N(x,y) = 2(x y) The equation is not exact because M_y =2(x y 1) # N_x = 2 But ( M_y N_x )/N = 1. Let's simplify it First dy/dx = (y/x 1)/(y/x 1) Taking y = vx dy/dx = v xdv/dx Therefore, dx/x = (v 1)dv / (v^2 1) Integrating we get log (1/x) logc = arctan (y/x) 1/2 log.

Let's multiply both sides times 1 plus 2y squared We get 1 plus 2y squared times dy dx is equal to y cosine of x We still haven't fully separated the y's and the x's Let's divide both sides of this by y, and then let's see We get 1 over y plus 2y squared divided by y,.  It is non homogenous equation Case (1) b₁ a ₂ = 0 3 2 = 1 ≠ 0 Case (2) a ₁ / a ₂ = b ₁ / b₂ Put 2 x 3 y = t Substitute the t value in dy / dx = ( t 1 ) / ( t 2 ) Therefore Let us take integration on each term. If in the equation y(y^2 2x^2)dx x(2y^2 x^2)dy = 0 we take y = xv(x) it reduces to (3v^3 2v )dx x(v^2 1)dv =0 It follows dx/x = (v^21)/(v(3v^2–2) After decomposition yields dx/x = dv/2v (1/12)d(3v^2 2)/(3v^2–2).

Because it doesn't follow the necessary condition of exact differential equation But if we divide the equation by $(x^2y^2)$ it follows the necessary condition Can you please explain the reason behind this?. ( 1) The correct equation is probably Eq. Being homogeneous DE means that all terms in it are of the same order (second) To solve, let y = xv (2) , then dy/dx = x (dv/dx) v (3) substitute (2) and (3) in (1), you get x dv/dx v = x^2 v/ (x^2 3x^2v^2) and x dv/dx = v/ (1 3v^2) v = (v v 3v^3)/ (1 3v^2) = 3v^3/ (1 3v^2).

1 y 1 (x) c 2 y 2 (x) = 0 for all x in the interval implies that c 1 = c 2 = 0 Otherwise, they are linearly dependent There is an easier way to see if two functions y 1 and y 2 are linearly independent If c 1 y 1 (x) c 2 y 2 (x) = 0 (where c 1 and c 2 are not both zero), we may suppose that c 1 0 Then y 1 (x) c 2 c 1 y 2 (x) = 0 or y.  The general solution of the differential equation (y^2 – x^3 )dx – xydy = 0 (x ≠ 0) is (where c is a constant of integration) asked in Mathematics by Jagan (.
