(\partial)/(\partial x)((x-y)/(x+y))

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

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

Solution steps

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

Treat

y

as a constant

Apply the Quotient Rule:

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

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

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

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

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

Simplify

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

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

d er i v a t i v e f (x) = \frac{( x ^{2} - 1 )}{2 x - 3}

\frac{d}{d x} ((ln (x))^{2})

\int \frac{6 x}{x ^{3} - 8} d x

\int_{0}^{2} (4 - x^{2}) d x
