Solve x((dy)/(dx))=y(logy-logx+1)...

Solve `x((dy)/(dx))=y(logy-logx+1)`

Text Solution

Verified by Experts

$$ \begin{aligned} &\mathrm{x} \frac{d y}{d x}=y(\log y-\log x+1) \\ &\Rightarrow \frac{d y}{d x}=\frac{y}{x}\left(\log \frac{y}{x}+1\right) \\ &\text { Put } y=v x \Rightarrow \frac{d y}{d x}=v+x \frac{d v}{d x} \\ &\Rightarrow v+x \frac{d v}{d x}=v(\log v+1) \\ &\Rightarrow \frac{d v}{v \log v}=\frac{d x}{x} \\ &\text { On integrating both sides, we get } \\ ...
