(\partial)/(\partial x)(x/(sqrt(x^2+16))*y)

\frac{\partial}{\partial x} (\frac{x}{x ^{2} + 16} \cdot y)

\frac{16 y}{( x ^{2} + 16 ) x ^{2} + 16}

Solution steps

\frac{\partial}{\partial x} (\frac{x}{x ^{2} + 16} y)

Treat

y

as a constant

Take the constant out:

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

= y \frac{\partial}{\partial x} (\frac{x}{x ^{2} + 16})

Apply the Quotient Rule:

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

= y \frac{\frac{\partial}{\partial x} ( x ) x ^{2} + 16 - \frac{\partial}{\partial x} ( x ^{2} + 16 ) x}{( x ^{2} + 16 ) ^{2}}

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

\frac{\partial}{\partial x} (x^{2} + 16) = \frac{x}{x ^{2} + 16}

= y \frac{1 \cdot x ^{2} + 16 - \frac{x}{x ^{2} + 16} x}{( x ^{2} + 16 ) ^{2}}

Simplify

y \frac{1 \cdot x ^{2} + 16 - \frac{x}{x ^{2} + 16} x}{( x ^{2} + 16 ) ^{2}} : \frac{16 y}{( x ^{2} + 16 ) x ^{2} + 16}

= \frac{16 y}{( x ^{2} + 16 ) x ^{2} + 16}

4 7 x^{2} + 5

x^{2} + 2

\int_{e}^{\infty} x^{2} ln (x) d x

\frac{d}{d x} (x x^{2} - 9)

x^{2} + y^{2} = 24
