(\partial ^2)/(\partial y^2)(xy^2-6x^2-3y^2)

\frac{\partial ^{2}}{\partial y ^{2}} (x y^{2} - 6 x^{2} - 3 y^{2})

2 x - 6

Solution steps

\frac{\partial ^{2}}{\partial y ^{2}} (x y^{2} - 6 x^{2} - 3 y^{2})

\frac{\partial}{\partial y} (x y^{2} - 6 x^{2} - 3 y^{2}) = 2 x y - 6 y

= \frac{\partial}{\partial y} (2 x y - 6 y)

\frac{\partial}{\partial y} (2 x y - 6 y) = 2 x - 6

= 2 x - 6

\int_{0}^{1} e^{5 x} d x

y \to 2 lim (\frac{y ^{2} - 4}{y + 2})

(2 x^{2} + 1)^{\frac{3}{2}}

\frac{d y}{d x}, x^{2} = \frac{5 x + 4 y}{5 x - 4 y}

\frac{2}{3 s + 1}
