 M = x 2 4xy 2y 2, N = y 2 4xy 2x 2 dM/dy = 4x 4y dN/dx = 4y 4x Therefore, dM/dy = dN/dx So, the given differential equation is exact On integrating M wrt x, treating y as a constant, On integrating N wrt y, treating x as a constant, (omitting 2xy 2 2x 2 y which already occur in ∫M dx) Therefore, the solution of. 0 23k views Solve ( x y 2 − e 1 / x 3) d x − x 2 y d y = 0 written 54 years ago by aksh_31 ♦ 23k • modified 54 years ago Mumbai University > First Year Engineering > sem 2 > Applied Maths 2 Marks 6 Year 14 needtagging. Differentiating x 2 y 2 – 2x – 4y 1 = 0 wrt x, we get `2x 2ydy/dx 2 xx 1 4dy/dx 0` = 0 ∴ `(2y 4)dy/dx` = 2 – 2x ∴ `d/dx = (2 2x)/(2y 4) = (1 x)/(y 2)` ∴ `(dy/dx)_("at" (x_1, y_1)) =(1 x_1)/(y_1 2)` = slope of the tangent at (x 1, y 1) Since,the tangent is parallel to Xaxis, slope of the tangent 0 ∴.

 If (x2y)dy/dx=2xy, what is the value of d^2y/dx^2 at the point (3,0)?. (b) 2 x y dx ( y 2 x 2) dy = 0 Here, M = 2 x y, M y = 2x, N = y 2 x 2, and N x = 2 xNow, ( N x M y) / M = ( 2 x 2 x ) / ( 2 x y) = 2 / yThus, μ = exp ( ∫ 2 dy / y ) = y2 is an integrating factor The transformed equation is ( 2 x / y ) dx ( 1 x 2 y2) dy = 0 Let m = 2 x / y, and n = 1 x 2 y2Then, m y = 2 x y2 = n x, and the new differential equation is exact. 2 ndOrder ODE 3 12 Second Order Differential Equations Reducible to the First Order Case I F(x, y', y'') = 0 y does not appear explicitly Example y'' = y' tanh x Solution Set y' = z and dz y dx Thus, the differential equation becomes first order.

They give you the integrating factor is x 2 , 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.

So the only critical point of f is (1,0) and it lies in the region x2 y2 ≤ 16 On the circle x 2y = 16, we have y2 = 16−x2 and g(x) = f(x, √ 16−x 2) = 2x2 3(16−x2)−4x−5 = −x −4x43 g0(x) = 0 ⇒ −2x−4 = 0 ⇒ x = −2 y 2= 16−x = 16−4 = 12 ⇒ y = ±2 √ 3 Now f(1,0) =. $$ y{\left(x \right)} \cos{\left(x y{\left(x \right)} \right)} 2 y{\left(x \right)} \frac{d}{d x} y{\left(x \right)} \frac{2 x e^{2 y{\left(x \right)}}}{dx.
