Explanation:tion of the differential equation \(\frac{\sqrt{x} d x+\sqrt{y} d y}{\sqrt{x} d x-\sqrt{y} d y}=\sqrt{\frac{y^{3}}{x^{3}}}\)
is given by
  1. \(\frac{3}{2} \log \left(\frac{y}{x}\right)+\log \left|\frac{x^{3 / 2}+y^{3 / 2}}{x^{3 / 2}}\right|+\tan ^{-1}\left(\frac{y}{x}\right)^{3 / 2}+c=0\)
  2. \(\frac{2}{3} \log \left(\frac{y}{x}\right)+\log \left|\frac{x^{3 / 2}+y^{3 / 2}}{x^{3 / 2}}\right|+\tan ^{-1} \frac{y}{x}+c=0\)
  3. \(\frac{2}{3} \log \left(\frac{\mathrm{y}}{\mathrm{x}}\right)+\log \left(\frac{\mathrm{x}+\mathrm{y}}{\mathrm{x}}\right)+\tan ^{-1}\left(\frac{\mathrm{y}^{3 / 2}}{\mathrm{x}^{3 / 2}}\right)+\mathrm{c}=0\)
