(\partial)/(\partial x)((9x)/(x^2+5y))

\frac{\partial}{\partial x} (\frac{9 x}{x ^{2} + 5 y})

\frac{9 ( - x ^{2} + 5 y )}{( x ^{2} + 5 y ) ^{2}}

Solution steps

\frac{\partial}{\partial x} (\frac{9 x}{x ^{2} + 5 y})

Treat

y

as a constant

Take the constant out:

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

= 9 \frac{\partial}{\partial x} (\frac{x}{x ^{2} + 5 y})

Apply the Quotient Rule:

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

= 9 \cdot \frac{\frac{\partial}{\partial x} ( x ) ( x ^{2} + 5 y ) - \frac{\partial}{\partial x} ( x ^{2} + 5 y ) x}{( x ^{2} + 5 y ) ^{2}}

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

\frac{\partial}{\partial x} (x^{2} + 5 y) = 2 x

= 9 \cdot \frac{1 \cdot ( x ^{2} + 5 y ) - 2 xx}{( x ^{2} + 5 y ) ^{2}}

Simplify

9 \cdot \frac{1 \cdot ( x ^{2} + 5 y ) - 2 xx}{( x ^{2} + 5 y ) ^{2}} : \frac{9 ( - x ^{2} + 5 y )}{( x ^{2} + 5 y ) ^{2}}

= \frac{9 ( - x ^{2} + 5 y )}{( x ^{2} + 5 y ) ^{2}}

2 x - \frac{1}{2 x}

\int_{0}^{1} 9 x^{2} + 1 d x

\int sec (\frac{2 x}{5}) tan (\frac{2 x}{5}) d x

\frac{d}{d x} ((3 x)^{\frac{1}{x}})

\frac{d}{d x} (ln (x) tan (x))
