Pregunta: Use multiplicadores de lagrange para calcular los valores extremos de f(x,y)= 3x² + y² sujetos a x²+y²= 4y

To find: The extreme values of the function $\mathrm{f}(\mathrm{x},\mathrm{y})=3{\mathrm{x}}^2+{\mathrm{y}}^2$ subject to the constraint ${\mathrm{x}}^2+{\mathrm{y}}^2=4\mathrm{y}$.

The constraint equation can ...
