How to solve a differential equation using the substitution $y=xv(x)$

299 Views Asked by At

I want to solve

$x\dot y'=y(2x+y)$ given $y=xv(x)$

I have put the given equation in the form $\dot y=2(\frac{y}{x})+(\frac{y}{x})^2$ and then said that $ \dot y=F(\frac{y}{x})=F(v)$. The equation can then be recast as $\frac{1}{F(v)-v}dv=\frac{1}{x}dx$. I am unsure how to begin to integrate this without ending up with some horrible exponentials. Any help would be greatly appreciated!

Considering the DE

$$ x y'=y(2x+y) $$

Making $v = 1/y$ we have

$$ v'+2 v+\frac 1x = 0 $$

which is linear...

NOTE

Being linear this last DE the answer can be written as

$$ v = v_h + v_p\\ v_h'+2v_h = 0\\ v_p'+2v_p + \frac 1x = 0 $$

here $v_h = C_0 e^{-2x}$ and now substituting $y_p = C_0(x)e^{-2x}$ (Lagrange constants variation method) we get

$$ C_0'(x) = -\frac{e^{2x}}{x}\Rightarrow C_0(x) = -\int^x \frac{e^{2t}}{t}dt $$

so

$$ v =e^{-2x} \left(C_0 -\int^x \frac{e^{2t}}{t}dt\right) = \frac 1y $$
