derivative of

y = \frac{2 x}{4 + x ^{2}}

\frac{2 ( 4 - x ^{2} )}{( 4 + x ^{2} ) ^{2}}

Solution steps

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

Take the constant out:

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

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

Apply the Quotient Rule:

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

= 2 \cdot \frac{\frac{d x}{d x} ( 4 + x ^{2} ) - \frac{d}{d x} ( 4 + x ^{2} ) x}{( 4 + x ^{2} ) ^{2}}

\frac{d x}{d x} = 1

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

= 2 \cdot \frac{1 \cdot ( 4 + x ^{2} ) - 2 xx}{( 4 + x ^{2} ) ^{2}}

Simplify

2 \cdot \frac{1 \cdot ( 4 + x ^{2} ) - 2 xx}{( 4 + x ^{2} ) ^{2}} : \frac{2 ( 4 - x ^{2} )}{( 4 + x ^{2} ) ^{2}}

= \frac{2 ( 4 - x ^{2} )}{( 4 + x ^{2} ) ^{2}}

\frac{d x}{d t} = \frac{2}{x}

x \to 6 lim ((x + 1)^{2})

\int \frac{1}{( 3 x + 5 ) ^{4}} d x

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