If X 1 Y Y 1 X 0 Then Prove That 1 X 2 Dydx 1 0
The first step is to find dy/dx To do this you must first expand the brackets x 2 y 2 2xy = xy 2 Then differentiate each term with respect to x dy/dx of (x 2) = 2x dy/dx of (y 2) = 2y(dy/dx) (Using the product rule with u=y 2 and v=1) this can be explained in more detail if necessary dy/dx of (2xy) = 2y 2x(dy/dx)Inverse Functions Implicit differentiation can help us solve inverse functions The general pattern is Start with the inverse equation in explicit form Example y = sin −1 (x) Rewrite it in noninverse mode Example x = sin (y) Differentiate this function with respect to

In differential equation show that it is homogeneous and solve it dy/dx = 2xy/(x^2 y^2) asked in Differential Equations by Devakumari ( Correction (after missing a sign) As kobe pointed out, the original DE is $$ (x^2y^2)y'2xy=0, $$ which as equation for a vector field reads $$ (x^2y^2)\,dy2xy\,dx=0\iff Im(\bar z^2\,dz)=0\text{ with } z=xiy $$ From the complex interpretation it is directly visible that this is not integrable, for that it would have to be an expression Expert Answer For this one we look for an integrating factor which will make the equation exact Let M = x − 2 x y − y 2 and N = y 2 Then M x = 1 − 2 y and N y = 2 y which is purely a function of y This tells us that there is an integrating factor μ ( y) which makes the equation exact which satisfies Clearly μ ( y) = e ∫ ( 1 y 2
