(\partial)/(\partial x)((4x)/(sqrt(x^2+2)))

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

\frac{8}{( x ^{2} + 2 ) x ^{2} + 2}

Solution steps

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

Take the constant out:

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

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

Apply the Quotient Rule:

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

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

\frac{\partial}{\partial x} (x) = 1

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

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

Simplify

4 \cdot \frac{1 \cdot x ^{2} + 2 - \frac{x}{x ^{2} + 2} x}{( x ^{2} + 2 ) ^{2}} : \frac{8}{( x ^{2} + 2 ) x ^{2} + 2}

= \frac{8}{( x ^{2} + 2 ) x ^{2} + 2}

(0, 4), (1, 1)

e^{- x}, 4, 0.25

\frac{\partial}{\partial x} (x z + x yz)

(x^{2} + \frac{1}{5}) 1 + 5 x^{2}

\int 5 x + 7 d x
