Use implicit differentiation where LaTeX:  \displaystyle y is a function of LaTeX:  \displaystyle x to find the derivative of LaTeX:  \displaystyle 3 x^{3} \log{\left(y \right)} - 12 \sqrt{y} e^{x^{2}}=12

Taking the derivative of both sides using implicit differentiation gives: LaTeX:   \frac{3 x^{3} y'}{y} + 9 x^{2} \log{\left(y \right)} - 24 x \sqrt{y} e^{x^{2}} - \frac{6 y' e^{x^{2}}}{\sqrt{y}} = 0  Solving for LaTeX:  \displaystyle y' gives LaTeX:  \displaystyle y' = \frac{x \left(- 3 x y^{\frac{3}{2}} \log{\left(y \right)} + 8 y^{2} e^{x^{2}}\right)}{x^{3} \sqrt{y} - 2 y e^{x^{2}}}
