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

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

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

Solution steps

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

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

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

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

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

x \to 4 lim (5)

\frac{d}{d x} (9 cos (3 x))

\frac{d}{d x} (4 a x)

x \to 2 - lim (∣ x ∣ - x^{2})

\frac{d}{d x} (\frac{5 x}{( x ^{2} - 1 )})
