(\partial)/(\partial y)((2xy^2)/(3+x^2y^2))

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

\frac{12 x y}{( 3 + x ^{2} y ^{2} ) ^{2}}

Solution steps

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

Treat

x

as a constant

Take the constant out:

(a \cdot f)^{'} = a \cdot f^{'}

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

Apply the Quotient Rule:

(\frac{f}{g})^{'} = \frac{f ^{'} \cdot g - g ^{'} \cdot f}{g ^{2}}

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

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

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

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

Simplify

2 x \frac{2 y ( 3 + x ^{2} y ^{2} ) - 2 x ^{2} y y ^{2}}{( 3 + x ^{2} y ^{2} ) ^{2}} : \frac{12 x y}{( 3 + x ^{2} y ^{2} ) ^{2}}

= \frac{12 x y}{( 3 + x ^{2} y ^{2} ) ^{2}}

\int x^{7} arctan (x^{4}) d x

\frac{d}{d x} (4 x^{2} + \frac{1}{x ^{2}} + 3 x^{4})

\int_{9}^{16} \frac{1}{1 - x} d x

\int x^{2} + 3 d x

\frac{d}{d x} (8 x - 5)
