$$x^{3} \sec{\left(y^{2}{\left(x \right)} \right)} \frac{d}{d x} y{\left(x \right)} + 3 x^{2} \tan{\left(y{\left(x \right)} \right)} + 4 y^{3}{\left(x \right)} \frac{d}{d x} y{\left(x \right)} + \frac{3 y^{2}{\left(x \right)} \frac{d}{d x} y{\left(x \right)}}{x_{2}} - \frac{2 y^{3}{\left(x \right)}}{x^{3}} = 0$$
