derivative of

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

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

Solution steps

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

Take the constant out:

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

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

Apply the Quotient Rule:

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

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

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

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

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

Simplify

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

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

\int e^{x^{2}} 4 x d x

\int_{1}^{3} x^{2} d x

x \to 4 + lim (\frac{- 3}{8 - 2 x})

\frac{d}{d x} (6 x^{1.5} - 4 x^{0.5})

\frac{\partial}{\partial x} (x e^{- y} + y e^{- x})
